Garcia said: "Antonio did well when he came on. He was probably a little nervous inside because of his age but it didn't show when he was called upon by the boss.
"Even though we're both from Spain, I didn't know too much about him before he arrived in the summer but I've heard he's very highly-rated back home. In training he's looked very impressive and he doesn't seem too overwhelmed about moving to such a big club in a new country at such an early age. I'm sure he will learn so much in training this season and if he gets a chance in the first team, he must make the most of it."
