How exactly is he doing a bad job?
I will say that his subtitutions and formation changes lately havent been good but saying hes doing a bad job isnt fair.
I think the constant resting of key players has been awful.
I think the playing around with formations constantly has been awful.
I think picking a different back line and players has been awful.
I think his substitutions have been poor, Winks and Janssen were pointless subs.
I think his in-game management has largely consisted of him sitting on his bench looking upset, which isn't good enough.
I think his post and pre match interviews have been poor, passionless and not what fans want to hear. He's largely been content, despite such a drastic dip in form.
I think his prioritisation of games/leagues/cups is awful, highlighted by last year going out of the FA cup, Europa League and then losing many games in the League in a short period.
I think not giving GK more game time has been awful.
I think the complete departure from last years formation and tactics have been awful, even when players have been fit to play largely the same 11.
I think the lack of pressing has been awful. When we do press (City and today first half) we don't look too bad. Then for some reason we simply stop doing it and look average. For Pedros goal we simply switched off and no one closed him down. Same for Moses.
I think selling Chadli was beyond awful and I think the transfers have made us weaker, not stronger.
On top of that his training seems to be exhausting the players and causing them injuries. We had almost no injuries last year, now we have loads. This is either down to pure luck last year or over-working the players this year. This is further backed up by the fact so many key players seem to need constant resting, when they didn't last year.
We were a good team last year, not because we had good players, but because the tactics and team were more than the sum of their parts. This year we look like less than the parts themselves, never mind the sum.
