Chelsea’s Chief executive Ron Gourlay said confirmed late on Monday that jose Mourinho will coach the Blues next season.
“I am delighted to welcome Jose back to Chelsea. His continued success, drive and ambition made him the outstanding candidate,” said Gourlay.
“It is our aim to keep the club moving forward to achieve greater success in the future and Jose is our number one choice as we believe he is the right manager to do just that.
“He was and remains a hugely popular figure at the club and everyone here looks forward to working with him again.
Mourinho, who won five major trophies in his first spell as boss between 2004 and 2007, has signed a four-year deal to replace interim manager Rafa Benitez as he begins his second stint at Chelsea.
The Portuguese took charge of his final Real Madrid game at the weekend, allowing Chelsea to confirm an appointment which has been an open secret for weeks.
Mourinho, who will address the English press on June 10, has won the Italian and Spanish titles since leaving Stamford Bridge and also led Inter to UEFA Champions League glory.
Rui Faria, Silvino Louro and Jose Morais will join the 50-year-old in west London as assistant first-team coaches, working alongside current coaches Steve Holland, Christophe Lollichon and Chris Jones.
