Is Chelsea's Performance Deteriorating Under Rosenior's Leadership?

Following Chelsea's recent 3-0 defeat to Manchester City, Liam Rosenior's tenure as head coach has come under scrutiny. Despite initially pointing out that Chelsea were fourth in the Premier League table since his appointment, their current standing has slipped to ninth after 11 games under his leadership. This downturn, combined with a dismal 8-2 aggregate loss to Paris Saint-Germain in the Champions League, has raised concerns about the team's trajectory under Rosenior. The pressure is mounting ahead of their upcoming match against Manchester United. Rosenior's initial success, with four consecutive Premier League wins, has given way to only one victory in the subsequent seven games. The significant gap between Chelsea and top-tier teams was highlighted by their losses to Arsenal, PSG, and Manchester City. Sky Sports' Paul Merson noted that Rosenior's team struggles against stronger opponents. While Rosenior has achieved impressive wins against Napoli and Aston Villa, the Manchester City loss has fueled supporter pessimism. With Chelsea averaging 1.54 points per Premier League game under Rosenior, their performance, although slightly improved from the previous season, remains the third-lowest for a Chelsea boss since 2004. This average falls short of the necessary points to secure a Champions League spot. If Chelsea continue at this rate, they would finish with 57 points, only five points above Liverpool's current total. The worry is that their current form might not even yield that, unless Rosenior can turn things around dramatically. Rosenior has reminded fans that even top coaches like Pep Guardiola and Jurgen Klopp needed time to 'sort things out' at their respective clubs. However, with 11 Premier League games into his tenure, the 41-year-old faces significant challenges, including a squad lacking experience and leadership, and the aftermath of a grueling Club World Cup campaign. Fans are entitled to expect more, especially given Chelsea's mental fragility, which has only intensified under Rosenior. The team has struggled with ill-discipline, receiving more cards than any other side since Rosenior's first game. With four points behind Liverpool and only six Premier League games remaining, Chelsea's prospects for a Champions League finish appear bleak. Their second-half collapse against Manchester City has raised concerns that they might need to start looking over their shoulders in the Premier League table. Nevertheless, there is some encouragement in the underlying numbers, with Chelsea's Premier League performances under Rosenior being much better than earlier in the campaign, according to expected goals. In fact, their net expected goals in the three months since Rosenior's appointment is the second-highest among Premier League sides, behind only leaders Arsenal. This suggests that Chelsea have created far better chances than they have conceded, outperforming Manchester City and Liverpool in this regard. Although results are paramount, especially at this stage of the season, Rosenior faces an uphill battle to convince Chelsea fans that he is the right person to lead the club forward.
