"I have only played two pre-season matches, I've played 15 official minutes and I've missed a penalty [in the Community Shield shootout] and they're already killing me, so I know what to expect."That's the price you must pay for such a big transfer. It's also something that motivates me...

I want to score goals, but a player can also be remembered for other aspects of play."Chelsea will play Burnley as their Premier League opener on Saturday at the Stamford Bridge.
