Inter Milan manager Jose Mourinho said he would be frustrated if his former players at Chelsea are extra motivated to beat him when the two sides clash on Tuesday. The Premier League leaders will visit Milan for the first leg of the last 16 clash in the Champions League. Media reports are already talking about Chelsea players' will to down their former boss. "If a Chelsea player is happier to beat me than to beat another manager I will be very sad," the Portuguese coach said. "I just don't understand that. I can't think there would be any special pleasure from that. "Just as if I am happier to beat them than to beat another team, then I think they have a reason to be very unhappy with me." Meanwhile, Michael Ballack said that Mourinho is already aware of all the aspects of Chelsea's game. "Mourinho always knew everything about every opponent, every player and every tactic," the Germany midfielder said. "He knows the players from his time here and only a few new ones have arrived, but the core of the team has remained the same.
