Alberto officially joined the Spanish side last week and will now spend at least the next 11 months on loan at La Rosaleda.
"I always like to have the ball at my feet. I'm a player who likes to assist, but also try and reach the finish myself," he told the club's official website.
"I've got a good feeling about this, I was really keen to join Malaga CF. I hope to perform well this upcoming season, both individually and as a team.
"I'd like to thank Malaga and Mario Husillos for giving me this opportunity. I now need to focus on working hard, I hope to perform well this upcoming season, both individually and as a team."
Alberto, 21, joined Liverpool from Sevilla last summer.
