Ronald Koeman criticised his Barcelona players for missing two penalties on Thursday as they needed extra time to end the cup run of third-division side Cornella and reach the Copa del Rey last 16.
Goals from Ousmane Dembele and Martin Braithwaite in extra time sealed a 2-0 victory for Barca but only after Miralem Pjanic and Dembele had both failed to score penalties in normal time.
