Come on. Martial a liability? He's had a pretty strong season, to the extent he's been playing. Maguire and Fred have, at worst, been mixed. There's plenty of examples of strong team performances with them in the starting XI. Yes Martial's fitness issues make him a no-go going forward and yes Maguire should be moved out and yes with Fred you always wonder if you're getting Good Fred or Bad Fred on any given day, but they are not bad players.
And sorry, but all this talk of our bench being "wafer thin" is bollocks. Injuries aside, it'd contain something like this: Malacia, Maguire, Lindelof, AWB, Fred, Sabitzer, Garnacho, Sancho. Do you see a lot of teams out there with benches who match that? The truth is, we have one of the deepest squads in the league. I'd like it to be better, yes, but this is not an area that is a clear competitive disadvantage for us.
