I want to get to a level where I am regarded as one of the best and coming to a club like Chelsea gives me the right platform to improve.

You can always be more professional.

You can never stop learning in football and I'm always trying to take little things on board that other players do.

I'm a striker. I feel I can have my greatest impact there because I'm free to roam around the pitch, take players on, have shots and create chances.

My success set me up for life, and it meant that I could retire from the music industry at 27 to spend time with my newborn daughter and my wife. My time away from the spotlight allowed me to rediscover my love for music, and I'm doing it for me now and no one else.

There are no secrets to success. It is the result of preparation, hard work, and learning from failure.

In New York, everyone's desperate for success, desperate for money and desperate to be accepted, but in London they're more laid back about things like that.

The financial crisis of 2008-09 was in large part the result of the so-called 'success' of people who did not understand their fiduciary duty. This kind of 'success' is extremely harmful to all of society.
