He said: “I know big clubs are looking at me. I want to reach the pinnacle of the game. I want to get the best players in the world playing with my philosophy, as I think that’s an invincible formula.
“If you play that way with the very best players, you can’t be beaten. I’ve proved with Seville how successful you can be, but we haven’t got the best players in the world.
“It’s difficult to say where I want to go. If I say Chelsea, Barcelona may decide they don’t want me. I want to be challenging for the Champions League with one of the big clubs.”
