First season in the PL for the new manager and former club legend. The goal was to return to Europe, improving the young players in the squad and playing better football in the process.
The board's strategy was to shift deadweight, while providing a considerable budget so the new manager could bring in players that fit the new playing style.

While there was an improvement in performance, the same was true about other clubs, with Man United and Newcastle performing particularly well. As a result Chelsea failed to improve on the last season, finishing 6th place again (1 point behind Newcastle) despite scoring 4 more points.
