Manchester City boss Roberto Mancini feels they're lucky to have David Silva.

Mancini says he's been following Silva since he was in charge of Inter Milan.

"I am just happy to be working with him," he revealed.

"I remember when I first saw him playing for Valencia against Inter in the Champions League. He was only young then but you could see his potential. He was astonishing. He has improved a lot in the last two years and now he is one of the best players in Europe, if not the world. He could play for Real Madrid or Barcelona, but I am glad to say he plays for Manchester City."
