Atletico Madrid on Saturday announced that they have completed the signing of young Argentine midfielder Angel Correa after his transfer was postponed in the summer because of a heart problem.

Correa, 19, underwent successful surgery in New York after the illness was detected during a medical with Atletico in May and has now secured his transfer from Copa Libertadores winners San Lorenzo.

Reigning Spanish champions Atletico, who are third in La Liga ahead of Sunday's home meeting with Villarreal, confirmed that Argentina under-20 international Correa has signed "for the remainder of this season and the following four campaigns."

Correa, who helped San Lorenzo win the Argentine title last year, is therefore tied to Atletico until 2019.
