The Chile international is nearing his competitive comeback after being cleared by the club's medical staff to resume training ahead of the cup final
The Chile international last featured for the Blaugrana in the 7-0 win over Rayo Vallecano in La Liga, and has since been out of action due to a thigh injury.
Alexis consequently missed the league games against Malaga, Espanyol and Betis.
Nevertheless, Barcelona have now announced on their official website that the former Udinese star has been given the green light from the club's medical staff, and has resumed squad training.
The 23-year-old is widely expected to make his comeback in the Copa del Rey final against Bilbao on May 25. Barca will be without injured duo Carles Puyol and David Villa.
