The Villarreal striker is wanted by Liverpool and Arsenal, while Barcelona and Real Madrid are known to be keen as well.
The Argentinean has enjoyed a fine debut season in La Liga, notching 20 goals in 48 appearances.
The 21-year-old is contracted with Villarreal until 2019 but does have a relatively modest buyout clause of 20m Euros.
He told Radio Vila-real: "No-one can guarantee what will happen in the future, but my idea is to be here when they call us.
"If Atletico come with €20m I will decide with my family and my representative.
"We will try to take the best decision but if they pay the buyout clause I think that everyone benefits.
"At the moment there is nothing, they are only rumours and my head is at Villarreal."
