Didn't follow Udinese, but from the last game I watched (Genoa-Udinese), Zapata was poor (the very Palladino who warmed the bench in Genoa made two assists under his feet). Some say it is because he is a CB who is not suitable for RB, but it's not like the Palladino case is related to his lack of speed or something like that.
Anyway, it's too harsh to judge by one match, but I have my doubts with him. Did you people really watch more than 8 games of Zapata to think him so highly?
