Liam Rosenior's tenure as Chelsea's head coach began with a grueling schedule of 11 games in 35 days, with limited time for training. Despite this, the team showed promise, winning eight of their first 11 games under Rosenior.
However, as the schedule eased and Rosenior had more time to implement his own tactics, the team's performance deteriorated. The head coach's preference for an aggressive, man-to-man press was exploited by opponents, and his authority was undermined by poor results, including an embarrassing 8-2 aggregate loss to Paris Saint-Germain in the Champions League.
Rosenior's commitment to his tactics and his handling of the team have been called into question, and his sacking after just a few months in charge is a testament to the fact that more time on the training pitch did not translate to better results for Chelsea.
