Manchester City boss Roberto Mancini is delighted with the progress of Deryck Boyata.

The young Belgian struggled against Hull City for Saturday's defeat at the KC.

Mancini told City's website: "If he keeps improving over the next couple of years, Boyata is going to be a fantastic player. He is going to make mistakes, he's still young and that's normal. But then the whole team did not play well in the first half at Hull, but they improved in the second half. We have to learn to start games better. We're a good team, but we have to have the right mentality."
