Chelsea face being trumped for Atletico Madrid ace Sergio Aguero by former manager Jose Mourinho.

The Sun says the Blues are in pole position to land the striker, though Inter Milan are circling.

They are due to meet Atletico Madrid representatives next week. But a top Atletico source said: "This is a battle between Chelsea and Inter.

"If the club decide to let Sergio go in January then he will go to one of those two clubs."

Aguero, 21, is top of boss Carlo Ancelotti's hit-list and Atletico have admitted they would be willing to off-load the Argentina superstar.
