I should still be manager at Chelsea, says José Mourinho

• Club have failed since I left, says Inter coach

• Return to Premier League remains an ambition

José Mourinho breezed back into Stamford Bridge last night to declare he was "home" and should still be Chelsea's manager. The Internazionale coach pointed out that while he has continued to accumulate silverware in Italy his former club have one FA Cup to show for the three years since his departure.

The Portuguese veered from an initially diplomatic script, marked by an admission that he would tone down his celebrations should the Italian champions eliminate their hosts from the Champions League this evening, to suggest some level of regret at the fracture of his relationship with Roman Abramovich after his glittering three-year spell in charge at the London club.

"I feel sorry but I look forward," said Mourinho. "I feel sorry because when I look at the big four teams from when I was in England, the managers are all still there: Sir Alex [Ferguson] is there. [Arsène] Wenger is there. [Rafael] Benítez is there. I did more than enough to be here. But the decision was made. Chelsea looked forward. I look forward. They move on. I move on. I keep winning important things. They keep winning ... something. They won an FA Cup.

"I have nothing to prove to Chelsea: to Chelsea's players, to Chelsea's fans, to Chelsea's board. The relations are great. When it's possible, happiness for me and happiness for them is the perfect situation. I don't believe I will be booed. I believe I will be clapped. But, for me, this game is just about getting to the quarter-finals. It doesn't mean anything else to me at all."

His only regret concerned the timing of his eventual departure, with Mourinho conceding he should have left Stamford Bridge on his own terms immediately after claiming the FA Cup in 2007. By then his relationship with Abramovich had fractured beyond repair, though the Portuguese was persuaded to remain at the club, only to be forced out in September of that year after a sluggish start to the following season.
