The 22-year-old signed from Sevilla in June, spent pre-season getting up to speed in his new surroundings and is now eager to experience competitive action.
"Football here in England is very quick, very rapid. It's a complicated league," Luna, one of six summer signings by manager Paul Lambert, told avfc.co.uk.
"For my own view, regarding my skills, it's great that this league is fast.
"I still need to adapt to things, of course, and feel I am all the time, but I believe it's good for me as I feel I have the characteristics to play here.
"I think I have good athletic abilities - I am quick as a player and that is important in a division like the Barclays Premier League.
"It's one of the best leagues in the world and I can't wait for the season to begin.
"It is close now and I am really excited about that. I can't wait because it's a new experience for me."
