"But I'm going through an amazing moment [at Barcelona] now."
The former Arsenal playmaker, who has won two European Championships and one World Cup with Spain, has been a regular this season for Barcelona, who currently lead La Liga on goal difference.

"This season I have felt more like myself, with more freedom and more secure with the way I like to play. It's not easy when you know you have to convince many fans how good you are and how good you can be for the team.

Fabregas said he regularly watched the Premier League on television.

"I have seen youngsters like Jack Wilshere, Tom Cleverley and Danny Welbeck play and they have got talent," he said.
"That's the thing England have been missing over the years - talent. They have got a great group of boys with amazing talent and they have to take advantage of that."
