Forlan has been strongly linked with a move away from Serie A side Inter Milan this summer.
The 33-year-old has scored just twice in 14 appearances since joining Inter Milan last summer.
Internacional vice-president Lucian Davi told Brazilian newspaper Lancenet: “If that information is true, we’ll be interested.
“Internacional will have to be creative to know how to handle this kind of situation. If Forlan becomes a free agent, we will have to work something out regarding his wages.”
