Mourinho was at Chelsea for three years

Former Chelsea boss Jose Mourinho has been appointed manager of Serie A champions Inter Milan.

Mourinho has signed a three-year deal with the Italian side in his first job since he and Chelsea parted company by mutual consent in September 2007.

The 45-year-old succeeds Roberto Mancini, who was sacked after leading the club to a third consecutive Serie A title last season.

Mourinho will be unveiled at a press conference at 1030 BST on Tuesday.

A statement on Inter's website said: "Internazionale announce the arrival of Jose Mourinho.

"The Portuguese coach has signed a three-year contract and will work alongside Rui Farias, Silvino and Andrei Villas Boas.

"The assistant coach will be Giuseppe Baresi."

Farias, Silvino and Boas were all part of Mourinho's backroom set-up at Chelsea, while Baresi is the head of the Italian outfit's academy.

The club added: "Thanking Roberto Mancini and his staff for the success obtained in four seasons as the leader of the team, all of Internazionale has the great pleasure to welcome Jose Mourinho and his coaches."

Mourinho has been heavily linked with the role at Inter and has reportedly been taking Italian lessons ahead of any possible appointment.

Inter appear to have drafted in Mourinho to help improve their success in Europe.

Despite their domination on the domestic front, they have struggled in the Champions League and were beaten at the last 16 stage by Liverpool.

"Serie A is feeling a little tender right now and perhaps not enjoying its status like before so having Mourinho joining is a very positive thing," said Italian football expert James Richardson.

While at Porto, Mourinho won the Uefa Cup in 2003 and the Champions League in 2004.

He also led Chelsea to the Premier League title in 2005 and 2006, while the Stamford Bridge side were beaten by Liverpool twice in the semi-finals of the Champions League in 2005 and 2007.

I would like to change very little of this squad which has won so much Inter president Massimo Moratti

He has already been linked with Frank Lampard and Didier Drogba and no-one would be too surprised if one, or both, joined Mourinho at Inter before the new season begins.

Inter president Massimo Moratti said: "I have read lots of names but I have yet to speak with him (Mourinho) about the transfer market.

"I would like to change very little of this squad which has won so much."

General manager Ernesto Paolillo added that there would be "few, but good players" arriving this summer.
