Argentina forward Hernan Crespo has moved to quieten the recent speculation linking him with a move back to Italian giants AC Milan. The 30-year-old is constantly tipped to leave Stamford Bridge in the summer but insists he is happy with the Premiership champions. Crespo, who has scored 10 goals this season, said: "I don't like this speculation. I think I'm a professional and I play with my heart at Chelsea. "In June I don't know what will happen as in the last four years I've always changed club. I want to stay here." "Complaining about my current situation at Chelsea is the last thing on my mind. In fact, it's quite the opposite. "My relationship with coach Jose Mourinho is very good and I understand that it's impossible to play every game, so from a working point of view, there is no issue," he told Chelsea's official website.
