The agent of Atletico Madrid's Sergio Aguero has suggested that either Arsenal, Liverpool or Manchester United have made a bid for his client.The 20-year-old Argentina international striker, who joined Atletico from Independiente in 2006, has proved to be a huge hit in the Spanish Primera Liga.

After forming a lethal strike partnership with Diego Forlan at the Vicente Calderon, Aguero finished the 2007/8 campaign as the third top scorer in Spain with 19 goals and also walked away with the Antonio Puerta award for Best La Liga Player.

Aguero, known as 'Kun', is valued at around the £35million mark by Atletico but despite the hefty price-tag, almost all of Europe's major clubs are interested in his services.

Now his agent Jose Segui is quoted as saying: "I've had interest from a leading English team and they've asked me to approach Atletico with a bid.

"I can't say more until I've spoken to the club about the offer.

"All I can tell you is that it's one of the best teams in Europe and it's not Chelsea."

United would have to be front-runners, but Arsenal could be interested in a deal if they were to sell Emmanuel Adebayor to AC Milan for a big enough fee, while Liverpool have also brought in funds after Peter Crouch joined Portsmouth for £11million.
