He (and all people who's been exposed to any kind of sports psychology) will tell you that you should put all your focus on things you can control, and you should put all focus on the task at hand. Divide and conquer. Create small goals that lead to a bigger goal, and focus on those small goals. In football (and pretty much all team sports), it's the next game.
In a recent interview he is totally open with that he watched the City game where Kompany scored his screamer, and he's completely open with his reaction as a fan of Liverpool. "Wow, that sucks.", or something in those lines. But when he turns off the TV he is 100% focused on the next game, his next task. He's accepted that he can't affect the result in City's games, but he can affect Liverpool's next game against Barcelona. And in that very interview he says that the Barcelona game was the same. He celebrated until he came in to the dressing room, then he was already focused on the next game.
He is basically saying what all managers, in all sports, are saying all the time: "We are focused at the task at hand. What team x does, what journalist x says, what manager x says, doesn't matter - I can't control it.
