Yeah but you said change the way we play. Having 2 DMs, including 1 who isn't blowing out his arse at 60 minutes, can enable us to play differently. We looked good against Chelsea in part because we dropped a midfielder between the CBs and pushed the FBs up. It's fine to do that and drop a forward player as our FBs create width & chances. Our problems are much deeper, but we can play differently with another DM in the squad2 DMs might be better than one of course but that means leaving a more attacking player out. He may well be an improvement on Kovacic but our problems go much deeper than that.
