Former Chelsea boss Jose Mourinho has fired a shot at his old striker Andriy Shevchenko by saying that he failed at Chelsea because he was too used to being treated like a prince at AC Milan.

Mourinho, now manager at Inter, wasted no time in making his comments about his City rival's new signing.

Mourinho said: "He was like a prince in Milan and at Chelsea our philosophy was different, we had no princes. Everybody needs to work like everybody else and prove he deserves to play."

Shevchenko completed a move back to AC Milan this week after spending two disappointing seasons at Chelsea following a £30 million transfer from Italy.

Mourinho made it clear that his observations were about Shevchenko the player, not the person. He denied that there was any problem between them.

"The truth is I never had a single personal problem with him and I wish him well for the future," he told Ford's FeelFootball.com website.

"I believe in the future he will again be a player of high quality."
