Villanueva has made no secret of the fact that he wishes to remain at Ewood Park and Audax Italiano chairman Claudio Tessa has no objection.
But Tessa claims that a host of anonymous clubs are interested in the players services, he told La Tercera: "We have already received several offers for his transfer. Two of them are concrete, one is from Europe and the other is from another continent.
"One of them wants to negotiate and arrange everything at once.
"Our idea is to wait a little bit longer because we know that Carlos has a good reputation. But if something very important appears, we can agree to arrange a deal at once.
"Carlos' idea is to stay in England. I was with Carlos in February and he told me he wanted to stay in England, but we will see what happens. I suppose he will stay in Europe."
