Chelsea are preparing a mega bucks swap offer for Atletico Madrid ace Sergio Aguero.

The Argentina international is set to be sold by Atletico in the summer with concerns his progress has stalled after over five years at the Vicente Calderon.

Aguero penned a new contract earlier this season - but significantly his buyout clause was reduced.

AS says Chelsea owner Roman Abramovich wants to bring Aguero to Stamford Bridge in the summer.

Abramovich is willing to offer £25 million cash for Aguero plus Nicolas Anelka, the former Real Madrid striker, in a swap for Aguero.
