( CNN ) -- Inter Milan boss Jose Mourinho insists he should not have been sacked by Chelsea , stoking the tension ahead of Tuesday night 's Champions League last-16 tie in London . Italian champions Inter hold a 2-1 lead after winning the first leg in the San Siro , with Mourinho making an emotional return to the club where he is still adored by fans after winning two English Premier League titles despite his acrimonious departure in 2007 . The Portuguese coach was axed by Chelsea 's billionaire Russian owner Roman Abramovich just two months into the season following a disappointing 1-1 draw with Norwegian club Rosenborg in the Champions League . He led Inter to the Serie A title in his first year in charge and the Nerazzuri top the Italian table again this season , though their lead has been cut to one point following Friday 's shock defeat by Catania .

Chelsea , meanwhile , have won only the English FA Cup since his departure , with his replacement Avram Grant and then Luiz Felipe Scolari being sacked before current manager Carlo Ancelotti took over from interim boss Guus Hiddink in July 2009 . `` I feel sorry but I look forward . I feel sorry because , when I look at the big four teams while I was in England , [ their managers ] are all there , '' Mourinho told reporters on Monday . `` Sir Alex Ferguson is here . Arsene Wenger is here . Rafa Benitez is here . 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 . `` The most important thing is the relation we have . No regrets , no big problems . Just respect . In football , coming back to an old team , it 's important to feel like I feel . It 's one of the most beautiful things in football . They move on , I move on . '' However , the 47-year-old admitted having one regret about his time at Stamford Bridge -- he would have preferred to leave on his own terms after winning the FA Cup in May 2007 . `` I would have left the day after the FA Cup final after my third season . The timing was wrong . I waited three or four more months more and , after that , I left in September and I did n't enjoy my time from then to the day I went to Inter , '' he said . `` For me , being away from football is too painful . If I had left Chelsea in May , I would have started the next season in a new club and I would not have been without football for six or seven months . '' Mourinho , who won the Champions League in 2004 before joining Chelsea , said he still wishes to return to England in the future . `` I have , as I said before , three things to do in my career . One is to come back to English football , another thing is to win the Spanish championship , because no-one has won Italian , English and Spanish titles . And another one , when I 'm old , is to coach my national team . But , for now , I would like to keep winning with Inter . '' Mourinho has had a difficult relationship with the Italian media since taking over from Roberto Mancini , now manager of English club Manchester City , and he has now come under more pressure following his latest falling-out with young striker Mario Balotelli . The 19-year-old , who was dropped by Mourinho for a month last season for reportedly not training hard enough , did not make the trip to England after missing the Catania game . Media reports claimed that the highly-rated Balotelli argued with Mourinho following a below-par performance in the previous game against Genoa , a 0-0 draw , claiming that he was ill. `` I do n't want to talk about him , '' Mourinho said . `` He wo n't be here . He wo n't be at the match . `` I can explain whey I called up the other 20 players . It 's more important to talk about the players who will be there , not those that are not .
