From an interview with CNN:
EUROPE NOT THE PRIORITY
"Both [the Champions League and the league] are important, but the Premier League is the road the heroes walk. It's the most important, in my opinion. Of course the Champions League is great - great to win, but if it's not possible to win both; my priority is the Premier League.
"The team is more mature and we play very well. The team is more compact, the spirit is better and the result speaks for itself. We don't lose many home games. And this is very important.
"If you want to be better, you need to practise, you need to train hard. This is what I do. In training and in games and I think if you want to be the best, you need to practise always.
"The past one year, two years, three, I think my motivation is not the money. My motivation is to be part of football history. This is what I think, this is what I try to do, training hard, play well, learn with my colleagues, win trophies. This is the most important for me."
