Barcelona striker Luis Suarez underwent surgery on a knee injury on Thursday and could be a doubt for their Copa del Rey final against Valencia later this month. Suarez played the full 90 minutes of Barca’s shock 4-0 defeat to Liverpool on Tuesday, which ended their hopes of reaching the Champions League final. But the club announced on Thursday that Suarez needed an operation, with the cup final just over a fortnight away on May 25. “Luis Suarez has an internal meniscal injury to the right knee and will be subjected today to an arthroscopy,” read a club statement.
