Atletico Madrid plan to re-write Sergio Aguero's contract at the end of this season.

The Argentine striker is tied to Atletico until 2011, but with a buyout clause of £22 million, the Spanish giants fear losing the player to a bigger club if they do not act.

Atletico plan to hand Aguero a bumper pay-rise, plus a hike in his buyout clause, to ward off the attentions of European rivals such as Juventus and Barcelona.
