Three months after Liam Rosenior took over as Chelsea’s head coach, the Blues face their most revealing test yet: a pivotal Premier League clash against Manchester City at the Etihad Stadium. The match offers a crucial opportunity to demonstrate meaningful progress under Rosenior—or expose persistent flaws that continue to undermine their Champions League aspirations.

A Season of Resilience and Regression

Rosenior stepped into the role following Enzo Maresca’s sudden departure on New Year’s Day, taking charge of a team that was fifth in the Premier League table and coming off a resilient 1-1 draw at the same ground three days earlier. That result—secured by a stoppage-time equaliser from Enzo Fernandez under interim boss Calum McFarlane—showcased Chelsea’s ability to perform under adversity. The squad had been hit by illness, injuries, and instability, yet still managed to earn a point against a rampant City side.

Now, with seven games remaining and just one point outside the top five, Chelsea are once again fighting for European football. Rosenior has had time to implement his philosophy, but the team’s trajectory remains inconsistent.

Form: Almost Identical, Slightly Improved

Statistically, Chelsea’s league performance has barely shifted. Under Maresca in the 10 games before January 4, they earned 16 points (W4, D4, L2). Under Rosenior, they have taken 17 points from 10 matches (W5, D2, L3). While the record shows marginal improvement, it’s not a significant leap forward.

One area of expected progress was discipline. Chelsea collected five red cards in the first 21 league games of the season but have seen only two since Rosenior took charge—though both came in consecutive matches against Burnley and Arsenal. Their average fouls per 90 minutes have dropped from 11.5 to 9.9, but troubling yellow card trends persist. The team now averages 2.6 bookings per game under Rosenior compared to 2.3 previously.

Certain types of cards—particularly for dissent and time-wasting—have actually increased. Moises Caicedo, on nine yellow cards, is one booking away from a two-match ban, adding pressure heading into the City fixture.

Leadership and Character Under Pressure

Chelsea had dropped 15 points from winning positions under Maresca—often due to mental lapses or late collapses. The hope was that Rosenior would instil better game management, but signs are mixed.

Early under his leadership, the team looked more composed. But recent implosions—such as blowing a lead in the first leg of their Champions League tie against Paris Saint-Germain (losing 5-2 after a 1-1 draw) and dropping points at home to Leeds and Burnley—suggest the psychological fragility remains.

“The most impressive thing is probably the players,” McFarlane said after the January draw at the Etihad. “One-nil down at the Etihad, interim manager, players falling ill on the day of the game, the day before the game, all the change. For them to regroup and take that information on and execute it speaks volumes about the characters we have at this club.”

That resilience is now being tested again. Once more, key players are missing: Enzo Fernandez is serving a two-match suspension after questioning his future at the club, while Reece James and Trevoh Chalobah are injured.

Positives Amid the Uncertainty

Despite the challenges, Rosenior has drawn improved performances from several individuals. Joao Pedro has emerged as a reliable focal point in attack, offering something the team lacked earlier in the season. Young talents Andrey Santos and Jorrel Hato have also gained confidence and are now dependable options.

A 4-1 win at Aston Villa in early March showed Chelsea’s potential on their day. But that optimism was quickly dampened by an 8-2 aggregate defeat to PSG in Europe, and a troubling trio of losses to Arsenal across all competitions since January.

Defensive Frailty Remains a Concern

One of the most worrying statistics: Chelsea have kept just one clean sheet in the Premier League under Rosenior—compared to eight under Maresca this season. Their defensive structure appears less resilient, and too often they rely on individual moments of brilliance rather than collective solidity.

The Final Test: Can They Rise Again?

As they return to the Etihad, much of the same uncertainty lingers—off-pitch noise, player absences, and recurring lapses in concentration. But so does the same potential for a statement performance.

Back in January, a depleted Chelsea dug deep and found a way to earn a point. Now, with Rosenior’s imprint more firmly in place, the question isn’t just whether they can repeat that feat—but whether they’ve truly improved since.

Sunday’s match won’t just reveal their standing in the title race. It will be a referendum on whether Rosenior has built something stronger—or if Chelsea are still circling the same old problems, hoping for a different result.
