The season in detail
José Mourinho's first Chelsea season produced the club's first league championship for fifty years. The team combined ninety-five points with only fifteen league goals conceded, a balance that made the title historically distinctive.
Chelsea lost only once in the league and finished twelve points clear. Frank Lampard led the recorded all-competitions scoring, while Petr Čech, John Terry and a settled defensive structure underpinned the exceptional goals-against total.
The League Cup supplied Mourinho's first English trophy before the championship was secured. Chelsea also reached the Champions League semi-final, where the European run ended against Liverpool.
The season is analysed as a sporting record rather than as an automatic consequence of new ownership spending. Resources changed the possibilities, but recruitment, selection and weekly consistency still have to be visible in any responsible account of the title.
Across 38 league matches Chelsea won 29, drew 8 and lost 1, finishing with a +57 goal difference. FA Cup: R5; League Cup: W; European Cup/Champions League: SF.
