The former Chelsea starlet believes he's returning to his best form at the Championship outfit.
And he revealed at 16 he turned down a five-year contract offer from Real Madrid.
"It was just before my seventeenth birthday. I was about to sign a permanent contract with Chelsea when my agent asked: 'Do you want to fly to Real Madrid with your family? They have a five-year contract for you'.
"'Wow', I thought. But I was a big Chelsea fan and I thought I was very close to breaking through. In retrospect, I might have done things differently, but then I thought I would break out at Chelsea.
"I do regret that decision a bit."
