His former Tenerife manager Alvaro Cervera, who played for Spain four times in the early 1990s, says Perez's attitude and application marks him out as a player of rich promise.
"Perez is quick with his feet and quick with his mind," said Cervera to the Daily Express. "He is a player who always gives his best in training and in matches, never anything less than that.
"His professionalism is something which he holds very true to his heart. He tries 100 per cent in everything he does and that is why he is a player of huge potential.
"He was determined to take the next step in his career and we could understand that. He wanted to test himself against the best and he wanted to move.
"It was the right decision for him to go, to try and move onto another level of football. It was a good deal for the club and for the player.
"It was a lot of money to pay for such a young player, but it was the right deal for both clubs and you have to pay good money for good talent."
