Denis left City for Barcelona as a young player.
“Maybe if I had stayed, I would be playing regularly there, but I took that decision to go to Barcelona and it was the right one for me because I played a lot of games for their first team.
“And to train with Lionel Messi and Andres Iniesta… brutal. Leo is the best. Andres is an example for me. I couldn't wait to learn from them and play with them, Messi trains how he plays. He loves to win: in every session, he has to win.
“But at City, I trained with David Silva and he is right up there. You guys in England fully appreciate Silva's brilliance but in Spain I am not sure everyone realises how amazing he has been. Silva has reached the heights of Xavi and Iniesta. I cannot speak with authority about City's entire history but Silva has, without question, been City's best player for the past decade."
