He's been a solid signing. The whole team has dropped off since the Brighton game - a combination of not having the squad and having injuries and niggles from playing 7 games in four weeks before the international break (and then our players traipsing around the world for that).
Doucoure was clearly instructed - like Delph on the other side - to play as full-back cover to allow Kenny to push up the other day. It didn't work at all and wasted our only midfielder with any ability of getting into the area at pace.
