The agent of Villarreal striker Luciano Vietto expects the Argentine to be on the move this summer.
Jorge Cyterszpiler has already confirmed the interest of Liverpool and Real Madrid, while Manchester United and Barcelona have also been linked in recent days.
Cyterszpiler told fichajes.com: "I think he might leave Villarreal in the summer.
"Luciano is a great player. It is normal that the best clubs in the world are after him. Great players play for big clubs, but we have to wait and continue to work.
"If big clubs come and make an offer, we need to talk. The offer must be very good, not only for us but also for Villarreal."
