Liam Rosenior’s tenure at Stamford Bridge is already under significant threat as the Chelsea hierarchy reportedly has "serious concerns" over his long-term suitability. Despite only being appointed in January, the former Hull City boss has struggled for the consistency and results required to meet the club's lofty ambitions.

According to Sky Sports in Switzerland, sources close to the west London club believe that the initial optimism following his January arrival has faded, leaving deep-rooted anxiety in the boardroom.

With the team sliding down the Premier League table and facing an uphill battle in Europe, the Blues' ownership appears to have already reignited the search for a new manager.While there has been no official statement from the club, the internal narrative suggests that a split is forming regarding the manager's future. Reports indicate that several key decision-makers believe Rosenior may not be in the dugout by the start of next season. This internal pressure is being amplified by the vocal frustration of the fanbase, who are growing weary of the constant managerial turnover. The "serious concerns" mentioned by club insiders with the Sky Sports report focus on a perceived lack of progress in playing style and the team's inability to secure results against their direct rivals in the race for Champions League qualification.Should Chelsea decide to pull the trigger on yet another dismissal, Rosenior is unlikely to be out of work for long. Despite his struggles in London, his reputation remains remarkably high on the continent, particularly in Ligue 1. French football observers have frequently praised his coaching methodology and man-management skills, which were highly regarded during his previous roles. Rosenior, for his part, undoubtedly remains publicly committed to his immediate objectives at Chelsea and it remains to be seen what the future holds.Add GOAL.com as a preferred source on Google to see more of our reportingThe upcoming schedule could serve as a final trial for Rosenior.
