Agent unsure over Aguero future

The 21-year-old has netted 44 league goals in 117 appearances for the Vicente Calderon side since arriving from Independiente in 2006, as well as winning 20 caps for Argentina.

Speculation earlier this summer predicted the highly-rated South American to seal a switch away from Spain, with Chelsea, Manchester United and Inter Milan all tipped to make big-money moves for the rojiblancos' star.

However, the transfer window slammed shut with Aguero still an Atletico player, while Madrid president Enrique Cerezo reportedly slapped a €60 million price tag on the striker's head.

Atletico's dismal start to the season - which has already resulted in coach Abel Resino losing his job - has prompted further reports suggesting Chelsea will renew their interest in the talisman, should they win their appeal against a transfer ban imposed by FIFA.

And the player's representitive, Jose Segui, has done little to quash talk of the forward departing in the not-too-distant future, after revealing he is not aware of the current situation regarding a possible move.

"Sergio to Chelsea in January? I don't know, it's a difficult question," he told Calciomercato.

"The only thing I can say is that I actually don't know anything.

"I don't expect any meeting with Atletico Madrid."
