Barcelona forward Isaac Cuenca has undergone a second operation on his troublesome knee and could miss the start of the new season.
Cuenca, who was operated on three months ago when on loan at Ajax, had a second meniscus operation on Thursday, the Spanish club have confirmed.
"The player Isaac Cuenca has undergone an arthroscopic stabilisation of the meniscus in his right knee," a club statement read.
"The estimated time on the sidelines will be around three or four months."
The 22-year-old made three appearances for Ajax before his injury.
