The Magpies attacker is in excellent form for Rafa Benitez' side and was instrumental in the 3-2 come-from-behind victory over Everton last weekend as he hit two goals including the late winner.
The Spaniard is now eyeing a call-up to the national team and says he will return to his homeland one day.
Perez was signed from Tenerife for just £1.5million back in 2014.
And he said: ”I am very grateful to Newcastle, but it is obvious that someday I would like to come back and play in La Liga.”
“To this day, I do not know [what the future holds]. I hope something very good.
“I believe that I have made progress these five years so that a good opportunity presents itself.”
Former Liverpool attacker Luis Garcia urged Spain manager Luis Enrique to call him up to his squad after watching his display against Everton
