The 34-year old Uruguayan striker has been heavily linked with a summer move to the Reds but told reporters that he is not yet planning to leave current club Internacional.
"But I have a contract here for another two years. I'm very happy here and I have a contract. Today you know, there are so many websites on the Internet to see if the source is right or not.
"But I would like to stay at Inter, until not only the (2014) World Cup, but until the end of the contract."
