Boca Juniors vice-president Juan Roman Riquelme can see Edinson Cavani joining Villarreal.
The Uruguay striker remains a free agent after coming off contract at Manchester United this summer.
Riquelme is a legend at Villarreal and revealed: "I spoke to him two and a half years ago.
"There was a lot of talk, but he was always very clear with me. When we have the chance for a star to come to our club, we do not hesitate.
"Cavani was very clear with me. He told me he had talked to Villarreal."
