Barcelona president Sandro Rosell insists they can maintain their success while tightening the club's budget.

Rosell says the club's academy - which has already seen the emergence of talents such as Xavi, Andres Iniesta, Leo Messi, Carles Puyol, Gerard Pique and Cesc himself - represents the future for Barca.

"It's important to invest in homegrown players," he said.

"That's our policy and it's the future of football."
