Barcelona made it safely into the last 16 of the Copa del Rey but they sure made hard work of Cornella and were forced to play extra-time for the third time in nine days which is not exactly what you want at this point in the season.
Ronald Koeman did get to rest Frenkie de Jong, Jordi Alba, and Marc-Andre ter Stegen, while captain Lionel Messi got the night off because of suspension and Sergino Dest was sidelined with a thigh problem.
Importantly Barca didn’t pick up any new injuries despite being forced to call on the cavalry.
