Is Liam Rosenior Unable to Beat Big Teams?

Chelsea’s embarrassing 3-0 home defeat to Manchester City reminded fans of their struggles against the big six. Despite starting mid-season in January, Liam Rosenior has been unable to break this trend. Chelsea have not beaten Manchester City in their last 10 games, with their last win being in 2021. Additionally, Rosenior lost to Arsenal thrice. Twice in the Carabao cup semifinal, and 1-0 last month at the Emirates. Chelsea hasn’t beaten Arsenal in 11 games; the last win was in 2021.  

Notably, Chelsea suffered their worst Champions League defeat against PSG, losing both legs in an 8-2 aggregate massacre. Rosenior’s losses to big teams are an alarming sign. His side has not scored a league goal since their 4-1 win against Aston Villa on March 4^th. This is, sadly, the only game among teams above Chelsea that Rosenior has beaten. Is he too weak against the bigger sides, or is he statistically unlucky? 

How he lost to Man City 

Rosenior’s conservative tactics were successful in restricting City in the 1^st half. City had more of the ball, but were unable to get past Chelsea’s players doubling up on their players. Cole Palmer hit the net, and Marc Cucurella scored a tight offside goal, all before City had their first real chance in the 33^rd minute, which was a weak shot saved easily by Roberto Sanchez. Against expectations, Chelsea were the better side. 

The script completely changed after halftime. Pep Guardiola made a slight adjustment – be more intense in pressing and winning second balls – and this completely disrupted Chelsea. From the very beginning, Chelsea struggled to string passes or get the ball from City. Guardiola used his physically stronger side to outrun and outmuscle Chelsea: which resulted in Nico O’ Reily outmuscling Andrey Santos to score the first goal, man of the match Rayan Cherki to skillfully glide across the pitch to assist Marc Guehi for the second goal, and lastly Moises Caicedo being triple pressed in his own box to lose the ball for an easy Jeremy Doku tap in.  

The most important factor is that after halftime, Rosenior was unable to adjust to the game-changing. Cherki, with his playmaking and incisiveness, took the game into his own hands and elevated City. It can be argued that Chelsea do not have players like Cherki, but Guardiola’s adjustments were able to elevate him while Rosenior couldn’t do the same for his attacking players, notably Palmer. Chelsea’s losing form after halftime is a dangerous pattern in Rosenior’s defeats. 

VS PSG. Chelsea’s worst UCL defeat 

The tie was effectively over in the first leg. Rosenior once again focused on playing the ball short to bait the opposition into pressing, and then quickly playing around it, creating space upfront for the forwards to attack. It was a very even game, but an open one for both sides. This was foreboding for Chelsea’s eventual loss, as the match became a game of chicken – whoever’s defence cracked first lost the tie. Chelsea lost.  

Rosenior specifically changed goalkeepers for this game because he believed Sanchez’s limitations as a ball-playing keeper hindered the team, but backup keeper Filip Jorgensen made him regret his choice. He had a few scares in the game, but a careless pass that was intercepted by Bradley Barcola led to an embarrassing lob by Joao Vitinha to score PSG’s 3^rd goal.  

You’d expect Chelsea to bounce back, considering the back and forth they have had throughout the game, but the way they conceded kills the momentum for them. The pressure ramped up with Chelsea once again being dominated on both sides of the ball. PSG manager Luis Enrique made further adjustments to his subs, and Kvicha Kvaratskhelia ended up being the super sub who destroyed Chelsea. 2 goals, both arguably saveable by Jorgensen, ended Chelsea’s UCL hopes.  

Many fans agree that Jorgensen’s mistakes ruined the game, but Rosenior’s inability to adjust to the changing momentum of the game – he called subs very late and continued his risky press-baiting style – gave Kvaratskhelia, a dribbling specialist, the perfect stage to run at tired defenders until he scored. 

The second leg was more or less the same as the first. Sanchez was back, but that didn’t change anything. Mamadou Sarr made his UCL debut with a horrific mistake, mistiming a clearance that led to PSG’s first goal in 6 minutes. Caicedo losing possession up the pitch gave PSG a breakaway, which they scored on 8 minutes later. When juvenile mistakes happen, tactics can’t win the game. Rosenior essentially waved the white flag, taking off Palmer, Joao Pedro and Enzo Fernandez right after halftime. 

Vs Arsenal in the league 

Mikel Arteta has quickly become Rosenior’s nemesis. Rosenior has already lost 3x to him, the most against a manager in his career. Arsenal scored both goals from a corner, and Sanchez’s inability to claim the corners got him dropped for the first PSG game.  

However, Chelsea were viewed as the better side despite this. They created more chances in open play; Arsenal were forced to rely on set pieces against the run of play. Nevertheless Chelsea lost because they were outmuscled by Arsenal for their corners, set piece defence has been a glaring weakness for Chelsea all season.

Vs Arsenal Carabao Cup 

The 2-3 home defeat in the first leg was the most damaging loss to Arteta. Sanchez’s failure to catch a corner led to Arsenal’s first. Sanchez failing to adequately stop a low cross led to the 2nd shortly after halftime. Unorganised defending gave Martin Zubimendi too much time in the box to score the 3rd.  Chelsea did create some chances. Rosenior made immediate substitutions after the 2nd Arsenal goal, including Alejandro Garnacho. His tenacity kept Chelsea in the game, scoring after Arsenal’s 2nd and 3rd goals to lead a comeback, but it wasn’t enough.  

Chelsea fans would be especially frustrated by this result, as all 3 goals conceded were largely due to player errors rather than a systemic problem. The game was winnable, and if fans felt it, Rosenior definitely did.  

The second leg didn’t go as expected. Chelsea was left reliant on shots outside of the box and corners. While it was a hard-fought game on both sides, Chelsea was humiliated when a last-minute attempt was intercepted, leaving former Chelsea player Kai Havertz with no hope and scoring the injury-time winner. 

The verdict: Can Rosenior secure Champions League?

 This isn’t the end of Rosenior’s big-match gauntlet. Games against Manchester United and Liverpool, who are still above Chelsea in the table, and Tottenham below, as the traditional big six, Rosenior has little time to reverse a dangerous pattern.  

Overarching numbers—no league goals since March 4th, a consistent second-half collapse in losses, and a dismal record against top-tier opposition—suggest something more structural than mere misfortune. Since March 4^th, Chelsea is 8-4 on aggregate in their league losses. 16-6 if counting the Champions League. 

Rosenior may point to individual errors that coaching cannot account for, but the broader trend is unforgiving: his Chelsea are outrun, outadjusted, and often outclassed when it matters most. If he cannot find answers in the upcoming fixtures, questions will arise on whether he’s the right man for a club that expects to compete with Europe’s best.
