At just 23, Barcelona defender Gerard Pique has launched a book on his life!

Pique writes about his times at Manchester United, Real Zaragoza and Barca.

Asked about playing for Pep Guardiola, Pique said: "In football he has given me everything. I can never thank Pep enough for the risk he took with me.

"I realize that it wasn't easy to play me so often in the beginning after not having played many minutes for Manchester United.

"It's not easy to manage a locker room like he has. There are many things for young players, everything goes very fast and it is easy to lose sight of the world sometimes."
