"There have been other figures within the game who said that they would prefer Leicester to finish as the champions, including the Swansea City manager, Francesco Guidolin. He said so on the eve of his club’s game at Leicester on 24 April, in which Swansea slumped to a 4-0 defeat. Pochettino believes that all of them have been unprofessional and he wants the issue to be raised and discussed at the next Premier League meeting.
“In football, our responsibility is to be professional,” Pochettino said. “When you are professional, it’s not to give your personal opinion. It’s always dangerous when something happens like that. Maybe in the last few weeks or months, we know the football people who maybe don’t behave like professionals. Maybe, in the next few meetings of the Premier League, the managers and also the staff, we need to say that, in future, we must be careful with all these comments in public.”
Pochettino made the point that he did not want to single out Fabregas and Hazard. “I don’t blame them,” he said. “It’s a general opinion. Sometimes my press conferences are boring because I’m very polite or political. No, I am professional. That’s a big difference. I don’t want to popular. I want to be professional. It’s easy to say big things against our enemy. ‘Oh, the people love me, I’m very strong, so I’ll say things like this.’ Come on! We are professional.
“The managers, the league, the players’ association – they need to say that we must behave professionally. We need to play, be honest and show integrity and be professional always. I like that when our opponent fights and tries to win but, for me, if we want to keep healthy football in the future, and not to be cynical and dishonest, we need to behave in a different way.”
