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.

Being nerdy just means being passionate about something, including everyone - the coolest people on Earth are passionate and therefore nerdy about something whatever it is, whether it's sports, or gaming, or technology, or fashion, or beauty, or food, or whatever.

A friend told me about a Nike competition, where they give you one minute to do tricks with a basketball. I wasn't going to go, but they were giving away free sneakers. I ended up coming in second place.

I wasn't concerned with the money stuff; I only wanted to play football.

The Czech tennis federation wasn't holding me back, but they could still pull the plug anytime they wanted.
