The Mexican ace scored 44 goals in 99 appearances in his first two seasons with Wolves, which has led to interest arriving from United and Juentus.
“I have three more seasons left [on my contract]," said the 29-year-old. “If I stay here at Wolves, I'd be very happy.
"We know that anything can happen and there could be a change. I'm open to everything.
“I already had the luck to play some games [in the Champions League for former club Benfica]. It's something incredible and it's in my plans to play again, but first I have to do what I have to do with Wolves."
