The 21-year-old has been linked with a January switch to a host of top clubs including Barclays Premier League leaders Chelsea, but insists he is unmoved by the speculation.

He told www.clubatleticodemadrid.com: "I am aware that there are always rumours about my future, but actually I am isolated from everything.

"I have always made clear my commitment to Atletico and everybody knows it. Do not pay much attention to what comes out. All I am doing is playing and worrying about the team, so these things do not affect me."

Aguero joined the Rojiblancos from Independiente in 2006 and is looking forward to continuing his progress at the Vicente Calderon.

"I have changed many things," he said, reflecting on his time in Spain. "I am happy to be spending my fourth year at Atletico Madrid.

"I realise that I have learned many things both on and off the field during my time here.

"Now I know the Spanish league very well and that has made me grow as a footballer.

"Over these years, I have played alongside great players which has taught me a lot as a player and as a person.

"I am a very young boy. A lot has already happened, but I still have much to learn.

"I came to Spain very young and have always been surrounded by older players. It can influence and make you mature faster."

Atletico, who finished fourth in La Liga last term, headed into the two-week winter break in 15th spot - just two points above the relegation zone.

Quique Sanchez Flores' side host third-placed Sevilla tomorrow, and Aguero knows it is up to the players to turn things around as soon as possible.

"We have not started the season well," he acknowledged. "The situation now is not good, but we must realise that we are practically the same players from last season except the odd change.

"We are the ones we have to look at the situation the team is in and pull forward, because we have no choice."
