They aren't good enough and that is thanks to the man that signed them.Never said they were world beaters but they're available; it's Carlo deciding to play 18 defensive players.
Carlo's job is to pick the team he thinks will get 3 points.
The fact he is consistently picking 5 at the back and at least two defensive midfielders every match should tell you how he rates those 3.
It's Brands job to build a squad full of options and he's done a very poor job of it. Carlo's hands are tied.
