Ancelotti: No Aguero bid planned
The Londoners come face-to-face with the Argentina international - who has netted 44 league goals in 122 appearances for the club since arriving from Independiente in 2006 - on Tuesday night at the Vicente Calderon aiming to seal their place in the Champions League knockout stages.
Chelsea, despite facing a two-transfer-window ban from signing players following the 'illegal' acquistion of youngster Gael Kakuta, have long been linked with a move for the prolific front-man, who has 20 caps for his country.
But despite former Atletico goal-getter Ruben Cano - who lifted the la Liga title with Atletico in 1977 - opining that Aguero will soon leave the club in search of silverware with another side, Stamford Bridge supremo Ancelotti said he is not planning to sign anyone in the near future.
"For his age, he [Aguero] is one of the most important and best-quality players in the world," he said ahead of Tuesday's clash in Spain.
"Aguero is very young, he is a fantastic striker and has a lot of quality.
"Every big club are looking at this player, but we are not thinking of buying anyone again at this moment."
