I'm a professional. I have to do my best.

I admire Arsenal and the philosophy that the young players have. Liverpool, with their Spanish players, they also have an incredible squad. And Manchester United and Chelsea are teams that are very big, like Real Madrid and Barcelona, with money and incredible players.

Through Common Goal, we're creating a collaborative way for football to give back to society.

I always said I was very grateful for Chelsea. I spent an amazing time of my career there, we won a lot of trophies, and I think I became a better player. I have great friends in the club, and I always wish the best for them.

Playing against Messi, as I've said before, is as tough a test of your concentration as any in football. At any moment, he can take the mickey out of you. Physically, it is demanding, but mentally even more so. You cannot switch off.

I love everything about this great game of football.

If you're a young kid out there, put away your Twitter accounts if you want to be a pro football player. Somebody's going to hack your account; somebody's going to cause you problems.

Sport allows us to engage in dialogue and to build bridges, and it may even have the capacity to reshape international relations. The Olympic Games embody perfectly this universal mission.
