Sergio Asenjo will decide his future at the end of the season but his agent concedes he is honoured to be linked with the likes of Chelsea and AC Milan.
Asenjo, who is rated as one of the best young goalkeepers in Europe, was snapped up by Atletico Madrid from Real Valladolid last summer.
The 20-year-old has impressed hugely for the Rojiblancos and now both Chelsea and Milan are said to be keen on landing him.
"The interest of top clubs like AC Milan and Chelsea is an honour," his agent Zoran Vekic told Calciomercato.
"In football anything is possible, but until the end of the season we will not take any decision.
"Atletico Madrid has made a major investment in him and together at the end of the season we'll evaluate the situation."
Vekic revealed that both Manchester United and Barcelona were tracking his charge before he moved to Atletico.
"We know that the Rossoneri have followed him but last year there were also Barcelona and Manchester United and there was also a deal with Fiorentina," he said.
