Copa del Rey fixtures between lower-tier sides and top flight La Liga outfits never fail to throw up unexpected twists.
The visiting Valencia hold a clear upper hand on paper as a long-established top division heavyweight, but their recent run of form across all competitions has been far from steady, with their consistency in both attacking and defensive phases still requiring notable improvement.
The home side UE Taf, by contrast, cannot match their opponents in terms of overall squad value or depth, but they have long demonstrated incredible fighting spirit whenever they compete in domestic cup ties. Especially when playing on their home turf, the underdogs often summon surprising levels of intensity that can pose huge threats and create massive problems for far more decorated top-flight opponents.
