Atletico Madrid fear they've lost young striker Adrian to Tottenham.
Marca says Tottenham are said to have put in a bid which will cover his €18 million release clause and also pay him triple what he currently receives.
In response to the bid Atletico have reportedly contacted Adrián and offered to extend and improve his contract.
But Adrián has rejected the offer from the Spanish club who has been unable to match the offer by Tottenham.
Atletico believes that Adrian has struck an agreement with the club - something which the player's agents have denied.
