Manchester United are among the clubs that have been linked with the Spain Under-21 international and although reports suggested an £18m bid had been lodged, Cerezo has denied hearing anything about a potential offer.
"No-one has asked me about him [De Gea] this morning," he said, as quoted by the Press Association.
"Ask Manchester [United] about it, but £18 million doesn't seem much to me."
The highly-rated goalkeeper forced his way into the first-team during the first half of the 2009-10 season after Sergio Asenjo was ruled out through injury.
The Atletico youth product recently signed a new contract at the club although could be tempted to move on in the summer if a big European side comes in for him.
