So I've read this article at goal.com. Where Negredo says that Messi could play in the premier league. The idea itself, blows my mind. I can't imagine messi in anything but a barca shirt. What is Negredo thinking? Anyway, here is the article:

Manchester City striker Alvaro Negredo says that he could see Barcelona sensation Lionel Messi moving to the Premier League in the next few years.

Messi has carved out a reputation as one of the game's greatest ever players with his remarkable performances for the Primera Division giants over the last decade, scoring over 300 goals for the club and winning the Ballon d'Or on four occasions along the way.

Negredo, however, believes that the Argentina international might grow bored of playing in Spain in the coming years and has urged him to join the Liga exodus to the Premier League should he ever decide to leave Camp Nou.

"I could see someone like Messi coming to England and following players like David Silva, Juan Mata, Santi Cazorla, David de Gea and myself. He could play well in any league in the world," said the Spaniard, as quoted by the Daily Mirror.

"Maybe in two or five years he will get bored with La Liga, want a change and come over here.

"The Premier League is the best place to be for the world's top stars. Having been here for a few months, it is better than I thought it would be. Your expectations go up here."

Messi signed a two-year contract extension earlier this year that binds him to Barcelona until 2018.

Well undoubtedly, if Messi plays elsewhere (IF, mind you), it'll be when he's close to retirement (late 30's). Doubt he'll go to a league as competitive and as physical as the EPL when he's 30 though.

Well its called devotion, as Totti and Gerrard he doesnt need to change the club he has all what he needs, a big salary, full visibility, world class teammates, even the coach is choosen by him ^^, so why should he leave ?
And considering his 250M buyout clause, who can buy him ?
He said that he wants to stay as long as Barça want him to stay, and after that, he wants to go back to Argentina wich is another heart choice, not a financial or competitivity choice.
And he has already 3 Cl and he scored in 2 finals against the best English side each time, what does he need to proove more ?

Speaking about Messi, sad to see another injury happening 6-8 weeks.
