The Blues have announced the appointment of the Portuguese for his second spell in charge at Stamford Bridge
Jose Mourinho has been appointed Chelsea manager on a four-year deal.
The Portuguese coach will replace Rafael Benitez, who has joined Napoli following his six-month interim spell at Stamford Bridge, in the Blues hot-seat.
Mourinho is returning to west London for his second spell as Chelsea manager. Since he left the club less than six years ago, the Blues have been through eight managers when caretakers are included.
The 50-year-old was Roman Abramovich’s first managerial appointment after his 2003 takeover and his most successful to date. In three seasons at Stamford Bridge, Mourinho delivered two Premier League titles, one FA Cup and two League Cups but did not win the Champions League.
He will hope to rectify that upon his return after the most difficult period of his career at Real Madrid.
Mourinho won the 2011-12 Liga title, ending Barcelona’s run of dominance in Spain, but could not progress beyond the semi-finals of the Champions League and conceded the Spanish championship back to Tito Vilanova’s team last season.
Abramovich has invested heavily at Chelsea in recent seasons as the team Mourinho helped to construct has aged, and the future looks bright for the two-time Champions League winner’s return.
