Maybe having a better structure at corners, which we were seemingly able to do under Bruce with the same players. Jak in goal instead of the sack of **** that is Marshall. A proper two strikers up front more recently than a week ago, before which he dropped Diomande who had been good for Mbokani instead of playing them alongside each other. Playing Clucas in CM where he was brilliant at the start of the season instead of at left back/left wing back where he has shown to be crap. The list goes on.
If you're on about the first few months of the season I agree completely.
The last few games he hasn't really got anything wrong other than ultimately being responsible for the defence being consistently piss poor, which has been the case all season.
