The 21-year-old striker has been linked with a big-money move to the Premier League ever since bursting on to the scene in Spain, with both Chelsea and United believed to be willing to pay the £40million that would persuade Atletico to part with their star man.
Thinking of England? Sergio Aguero has been linked with a big-money move to Chelsea or Manchester United
It's unlikely that Argentine international Aguero - son-in-law of Diego Maradona - will commit to a move before this year's World Cup finals, but he admits that it may not be long before the Spanish club decide to cash in.
Aguero said: 'I have enormous affection for Atletico but you cannot say I'll be here for ever.
'At the moment, I'm happy here and love the fans. I hope I can do well for them on the pitch.'
Aguero has already been tipped to succeed his fellow countryman Lionel Messi as the best player in the world, and is looking forward to playing a prominent role alongside the Barcelona man in South Africa this summer.
'Any player would like to be told he's the best in the world but I still have things to learn,' said Aguero. 'It'll be my first World Cup and, God willing, I'll help Argentina reach the final. It's important to have a dream.'
