Not only is their defense and keepers are poor, they don't have that resolve at the back. Teams that can have the mix of going direct, play the ball into space, and bypass their initial press will have their chances.Plus their defense is shit and they've got a clown in goal. Like West Ham, if their opponents are up for a game, they can be beaten.
9 have been from the bench.Wiki says he played 12 games in the league and 14 overall for them. One goal in such number of matches is pretty low, though I don't how many minutes he played out of these 14 matches.
I actually checked Transfermarket and he only played 618 minutes this season out of these 14 matches.9 have been from the bench.
