How Consistent Was Every Premier League Lineup This Season?

What our newest metric STABLE can tell us about Arsenal’s surprising title challenge and Chelsea’s face-plant.

Before the 2022-23 Premier League campaign kicked off, there was a buzz around St. James’ Park that hadn’t been felt in quite some time: optimism. After years of bottom-half finishes, relegation scraps and mediocrity, it finally felt like Newcastle United was building a team its fans could believe in. Driven by a cohesive and formidable defensive unit — a four-man back line and goalkeeper who have played more than 78 percent of the season’s minutes together — the Magpies more than delivered, blowing away their most bullish expectations to earn a top-four finish and a place in next year’s Champions League.

To evaluate the consistency of Newcastle’s squad, along with every other Premier League team this season, we created a new metric called STABLE (Similarity of Teams And Balance of Lineups across Every match) that tells us how similar each team looked every time it took the pitch. A team whose starting lineups and substitutions stayed exactly the same for every match would have a STABLE score of 100 percent, while a team that switches its entire lineup from one match to the next would earn a 0 percent. Looking at a team’s season through this lens, especially in comparison to its performance on the pitch, can tell us something about its cohesiveness (see, for instance, Newcastle’s stalwart defensive back line), strategy (like Pep Guardiola’s constant rotation of Manchester City’s starting 11) and luck (yet another injury-riddled Liverpool season).

Consistency has put Arsenal and Newcastle ahead of schedule, with Chelsea lagging way behind

The two most consistent teams this season by STABLE, Arsenal and Newcastle, just so happened to be the two biggest overperformers, based on actual points earned per match versus predicted points per match from our preseason forecast. But there isn’t actually a tidy relationship between consistency and success. Teams can have relatively steady squads that drop points match after match (sorry, Everton supporters). And there are many reasons clubs find themselves on the inconsistent end of the STABLE spectrum. For the richest clubs with deep rosters, inconsistency can be more of a feature than a bug. Ever-changing lineups can also point to a team devoid of any cohesiveness, struggling to establish who its best squad really is — or a team that simply suffered lots of injuries and bad luck. And in the worst-case scenario, it can signal all these at once (here’s looking at you, Chelsea).

But while we can’t just look at a team’s STABLE metric and see evidence of a good or bad year, it can still tell a story. By visualizing each team’s lineup throughout the year, we created a unique fingerprint for each club that offers nuanced detail about a team’s identity and its season.

Let’s zoom into a few of these charts to take a closer look at what these fingerprints can tell us about specific squads and players this year. First up is Arsenal, whose consistency helped the Gunners outperform expectations and mount a surprising (but failed) title challenge.


ARSArsenal86.6%STABLE

Arsenal Football Club entered the season aiming to earn a top-four spot and return to the Champions League after six years away. So while ending such a promising season without a trophy after spending almost the whole campaign at the top of the table will be brutally disappointing for the Gunners, any reasonable supporter would’ve given you a resounding “yes” if you asked them at the beginning of the season if they would take a second-place finish.

Much of their reemergence can be attributed to a sense of stability and identity Mikel Arteta has developed within a tight, cohesive nucleus of young and talented players. Goalkeeper Aaron Ramsdale and center back Gabriel have only missed a combined nine minutes across all Premier League competitions. Starboy winger Bukayo Saka has been an almost permanent fixture in Arsenal’s front line and has developed into one of the league’s best playmakers — only he and Liverpool forward Mohamed Salah have registered double-digit goals and assists in the Premier League this season. And captain Martin Ødegaard has shown remarkable leadership, calm and dynamism in the ever-important midfield. In Arsenal’s 37 matches, Arteta has used only 22 unique starting 11s, tied with Newcastle for the lowest figure in the league.

The biggest shake-ups to Arsenal lineups have come through injury — most notably to striker Gabriel Jesus, who missed 12 matches after sustaining a knee injury during the World Cup, and center back William Saliba, who has been out since suffering a season-ending back injury on March 16. Arteta employed a next-man-up approach to steady the ship, slotting Eddie Nketiah and Rob Holding in the starting 11 for long stretches, minimizing the impact on Arsenal’s STABLE score. Arsenal will probably need to upgrade their roster and build depth over the summer if they want to challenge for trophies next season, but their small and close-knit squad has outpaced expectations this year.


MNCManchester City74.1%STABLE

Manchester City are top of the Premier League once again, having already clinched their fifth title in six years after spending the vast majority of the season behind Arsenal. City goes into the home stretch of the season with the league’s second-lowest STABLE score, at the opposite end of the spectrum as the Gunners. Their lack of consistency is a concerted strategy by manager Pep Guardiola, who constantly rotates lineups from one match to the next — so much so that fans refer to the challenge of predicting his starting lineup as “Pep roulette.” In 36 Premier League matches this season, Pep has used 35 unique starting 11s.

Manchester City have the luxury to use fluid, ever-changing lineups because of their incredibly deep roster of all-world talent. Seemingly endless wealth from Emirati owner Sheikh Mansour and years of sustained success have made City an attractive destination for star players looking to win at the highest level, most recently Jack Grealish and Erling Haaland. Pep moves players who would be regular starters at pretty much any other Premier League club to and from his bench as he sees fit, keeping them fresh for future matches while keeping opposing tacticians guessing. We’ll see if this strategy finally pays off in Europe as City go for their first Champions League win against Inter Milan, but it’s been a well-oiled machine domestically as the Cityzens have established themselves as a Premier League juggernaut.


NEWNewcastle United85.5%STABLE

If you’re a Newcastle United supporter, 2022-23 was about as close to a dream season as you could’ve hoped for. Finishing top-four and qualifying for the Champions League is a massive achievement for the Magpies, who hadn’t finished higher than 10th in the Premier League table since the 2011-12 competition (and had even suffered relegation in the 2015-16 season). Newcastle’s overperformance boils down to three main factors: money, player development and defense. Saudi Arabian ownership has flushed Newcastle with cash and they’ve used it adeptly, bringing in talented players in key positions of need like midfielder Bruno Guimarães and forward Alexander Isak. Manager Eddie Howe and his staff also have found a way to make their existing players so much better, elevating the likes of Joelinton, Miguel Almirón and Sean Longstaff into top-level Premier League players.

Newcastle’s tactical success is founded on their defensive unit, which is one of the best in the league — they’ve conceded the second-fewest goals of any club, allowed the second-fewest expected goals against and are tied for the second-most clean sheets. Their core defensive unit of goalkeeper Nick Pope and defenders Kieran Trippier, Fabian Schär, Dan Burn and Sven Botman have formed a cohesive and formidable back line. It’s become rare to see a Newcastle team without them on the pitch — 31 of the Magpies’ 37 starting lineups this season have included all five of those players.


CHEChelsea67.6%STABLE

Conversely, if you’re a Chelsea supporter, 2022-23 was about as much of a disaster as you could’ve imagined. It’s been arguably the most disappointing season in the club’s history, given its lofty aspirations and record-setting spending. Chelsea had finished outside the top six only once since the 1995-96 season — a blip followed by appointing manager Antonio Conte in 2016 and winning the league the next season. But the Blues come into the last weekend in 12th place, sitting 6 points closer to relegation than they are to the top six.

It’s been an unthinkably disjointed first full campaign for the new Chelsea ownership consortium that includes Clearlake Capital and Todd Boehly, who have employed four different managers and spent an astounding €611 million on 17 new players across the summer and winter transfer windows while failing to address the team’s key needs in the short term, especially in front of goal.

Such a massive influx of players in a short period of time bloated the Chelsea squad to the extent that players reportedly had to change in the hallway, sit on the floor in team meetings and split into separate training sessions. What resulted was a team lacking any semblance of identity or cohesion. Compounded by a number of long-term or lingering injuries affecting key players such as N’Golo Kanté, Reece James, Ben Chilwell, Thiago Silva, Wesley Fofana and Armando Broja (just to name a few), Chelsea never figured out a lineup that worked — in 36 matches, Chelsea have used 36 different starting 11s. At this point, Chelsea supporters can do nothing more than be relieved that the team avoided being sent down to the Championship and hope that the team shows any sense of identity or improvement next season under presumed new head coach Mauricio Pochettino.

Methodology

To calculate a team’s STABLE score, we first count how many total minutes each player played in every match and compare that to how many minutes that player played in the club’s previous match. We then calculate the sum of the absolute value of the differences between those two minute counts across all players and matches. Then, we divide that sum by the total number of minutes played by all players in a team’s season (90 minutes per match × 11 players × the number of matches a team has played) to yield the percent of a team’s total player-minutes that were inconsistent from match to match.
The results of the above calculations give us a number between 0 and 200. To make it easier to interpret, we then scale that figure to fall between 0 and 100 percent. Because STABLE counts when players play either more or fewer minutes than their previous match, and also counts differences for players who might not even be on the pitch in a given match (if they played in the previous match), it can actually double-count inconsistent player minutes. Take, for example, a team who played one set of 11 players a full 90 minutes in one match (“Match 1”) and played a totally different set of 11 players 90 minutes in its next match (“Match 2”). To evaluate the STABLE score of this team in Match 2, we first need to count all the minutes that differed between Match 2 and Match 1 for each player, regardless of whether they actually played in Match 2. This total would be 1,980 — 90 minutes for all 11 players who played in Match 2 (but not in Match 1), and 90 minutes for all 11 players who played in Match 1 (but not Match 2). Then, we calculate the percent of this team’s player-minutes that were inconsistent from Match 1 to Match 2 by dividing that sum of 1,980 by the 990 minutes played by all players in Match 2 to yield 200 percent. Since we want STABLE to range from 0 percent (completely inconsistent team) to 100 percent (completely consistent team), we need to then divide this percentage by two before finally subtracting it from 100 percent to yield our final STABLE score for a team’s season. In this most extreme example, our team’s STABLE score through two matches of the season would be 0 percent.

Starting lineups and bench selections for each Premier League match, along with when any player is put on or taken off the pitch and player positions, come from ESPN. Players can be taken off the pitch either because they are subbed off for another player or ejected after receiving a red card or second yellow card. Stoppage time at the end of the first half is included in the 45th minute and stoppage time at the end of the match is included in the 90th minute, so each match contains a total of 90 minutes. Any player subbed on is attributed a minimum of one minute played — players subbed on in stoppage time after the 90th minute log one minute played, and players subbed off after the 90th minute log 89 minutes played.
