Forlan's agent Daniel Bolotnikoff told skysports.com that a number of clubs had made enquiries over his client, but insisted he was currently happy in Madrid.
Bolotnikoff said: "I have received calls from big European clubs requesting information about the situation, but I am not authorised to give their names.
"My answer is always the same. Atletico Madrid will decide on this subject.
"Diego is enjoying a great season in front of goal and is happy in Madrid, but at the end of the season we will be in a better position to evaluate the situation.
"Forlan could have a big role in England."
