Reports in Italy claim new Inter coach Jose Mourinho is keen to bring the 20-year-old to the San Siro next season, and his club have launched a bid of 25million euros plus midfielder Dejan Stankovic.

That offer, which fell short of 'El Kun's' release clause of 55million euros, was rejected but other reports suggest Mourinho's former club Chelsea are considering stumping up the mega fee.

But Cerezo claims to be unconcerned by the speculation, insisting Aguero will not be sold because he does not want to leave Madrid.

"El Kun is not for sale. He is a basic part of this Atletico team and will be for the next few seasons," Cerezo told Spanish newspaper Marca.

"I always say a player leaves a team when he wants to, and el Kun does not want to leave nor do we want him to go.

"Aguero wants to play here and we want him to play here. Enough said."

He added: "There has been no offer for the player nor do I believe there will be one."

There is a large amount of speculation surrounding Los Colchoneros at present, as they are believed to be interested in signing Florent Sinama-Pongolle, Paulo Assuncao and Czech Republic defender Tomas Ujfalusi.

While Cerezo claimed there was "nothing concrete" with any player yet, of Ujfalusi he added: "He is one of the players who interests us, who we want to have next season, but for the moment there's nothing signed.

"He's an international, captain of his national team and a great player. Atletico are interested in all the great players."

Earlier on Monday the Czech star told radio station Onda Madrid: "Atletico are a great club, a compact and strong side who had an extraordinary season last year.

"I can't say anything more until there's something signed."
