Chelsea have revealed that Jose Mourinho has agreed to take charge of the club for a second time.

The Portuguese coach spent three years at Stamford Bridge up until September 2007, when he was believed to have fallen out with owner Roman Abramovich.

However, during his stints with Inter Milan and Real Madrid, the pair are believed to have patched up their differences, which has resulted in the 50-year-old's reappointment this afternoon on a four-year contract.

"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 will officially be unveiled to the media next Monday.
