Both Sky Sports and The Telegraph have confirmed Chelsea have “strong interest” in Aguero, but they aren’t sure City would want to sell their prized asset to strengthen a rival.

And according to the Independent, despite the possibility that Aguero will be pushed even further down the pecking order at the Etihad Stadium, City are maintaining their hardline stance against Aguero leaving. The City board sees the Argentinean striker as their most important and marketable player and not one who can be properly replaced.

Aguero still has three years left on the contract which he extended last season.
