Sergio Aguero's agent Jose Segui claims he knows nothing about Manchester United's supposed interest in the Atletico Madrid striker.

Speculation is rife that United are set to use some of the £80million they are due to receive from the sale of Cristiano Ronaldo to Real Madrid to sign Aguero, while Chelsea, Barcelona and Inter Milan are also said to be interested.

"I have no information about this offer from Manchester United," Segui told Calciomercato.it. "I have not been contacted by anyone, nor by other teams."

Reports suggest United are preparing a 52 million euro offer, eight million less than the Argentina international's buy-out clause which Atletico president Enrique Cerezo insists any club will have to meet to persuade them to even think about selling.

Segui added: "I have not read president Cerezo's comment, the only thing I can say with certainty is that the player wants to stay at Atletico.

"Inter? I have not had any conversations with them.

"Honestly, I don't know if Atletico have met other clubs."
