With him scoring so much, it's hard to criticise him. Also, the team are poor at defending... it's hard to single Manning out. But I agree, it would be nice if he could up his defensive game. There are some good challenges from him and some good defensive headers, but definitely room for improvement. I think he's maybe too eager to attack, which makes sense considering he was originally a midfielder.
Been quite a few chances for some tap-ins. Need someone in the box to take advantage of the balls coming in
