Jose Mourinho has been officially announced as the new Chelsea manager after putting pen to paper on a four-year contract.
Since leaving the club in 2007 Mourinho has taken charge of Inter Milan and Real Madrid, winning three league championships, two domestic cups and the Champions League.
The 50 year old confirmed just a matter of weeks ago that he would be leaving Real Madrid at the end of the season and, after flying to London yesterday, has now been confirmed as Chelsea's new manager.
"I am delighted to welcome Jose back to Chelsea. His continued success, drive and ambition made him the outstanding candidate," chief executive Ron Gourlay told the club's official website.
"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 has had a difficult time in Spain over the last few months as reports of player revolts and disharmony led the former Porto boss to explain that he wanted to return to a destination where he felt loved.
Chelsea fans still remember Mourinho warmly for his achievements with the club after being appointed back in 2004. He won his first trophy in February 2005 by defeating Liverpool 3-2 in the League Cup final and then went on to win the league title in his first season with a record 95 points.
The west London club won consecutive league titles under Mourinho who also delivered a League and FA Cup double in 2007.
However, in September 2007 Mourinho departed by mutual consent and continued to excel first in Italy with Inter Milan, and then in Spain where he managed to beat Pep Guardiola's Barcelona side to the league title.
Mourinho will bring Rui Faria, Silvino Louro and Jose Morais who will all work under the same title as assistant first team coach, while current members of the coaching staff; Steve Holland, Christophe Lollichon and Chris Jones will also remain at the club.
Mourinho will be officially unveiled at a press conference at Stamford Bridge on Monday 10 June.
