Joe Hart.
I thought every keeper did very well though, in the EPL keepers tend to play to their limits. So... Hart was probably the only keeper that underachieved last season.
Vorm has under performed since Rodgers left Swansea.
Miglonet has been pretty woeful since joining Liverpool, you simply can't make as many mistakes as he does as a goalie, here's hoping we get Valdes.
Steklenburg was disappointing when he joined Fulham aswell.
Hart WASN'T bad at all
Joe Hart :)
De Gea i lost count of how many times he picked the ball out of the net.
