Of course they are ultimately to blame, but Mourinho has done plenty of damage himself. The board are not directly influencing player performances, they have put Mourinho and his team in place, backed him (until this summer anyway) and now he's tearing everything apart and upsetting the players. Which is exactly what he's done before.
It would be a shame to lose players like Pogba, Martial and De Gea. Sure, Pogba hasn't done well in general, but if he could play with freedom and confidence, he has the ability to completely run games unlike any other player.
There is only one solution here. Mourinho has to go.
The thing is Pogba is playing into JM's hands the way things are going - if Pogba actually played well and ignored the tactics that are supposedly stopping the team performing then everyone would rightly be looking at JM. Because Pogba is playing regularly so poorly, he has to take some of the blame, after all its only him that's misplacing so many passes / looking so lazy on the field barely even jogging let alone actually running etc etc etc.
He could have bossed the game at Southampton single handedly if he had wanted to to spite JM, but instead he wasn't worth even being on the field...and that's 100% Pogba's fault.
Im not absolving JM of fault, he has to be accountable for plenty, but it wont do any good if the club stay the same and just appoint another manager - we will just sink further and further down and end up relying on worse players (because those will be the only ones willing to go to utd)
. He has had the money, the backing of the money men .
That's factually incorrect - two years ago Woodward refused to sign Perisic , and there are other notable refusals of similar players that JM wanted. so no the money men haven't backed him completely.
Its also highly unlikely even 1/2 the players that have been signed since JM arrived were actually his choice , rather than the club (for one its definite that Pogba wasn't JM's choice from the sheer amount of time it would have taken to get the deal done, and most likely that Sanchez wasn't JMs choice either) - and JM certainly wasn't backed last summer in the slightest.
Only three were probably JMs choice, Lukaku, Matic and Bailly - the rest are most likely board / EW's choices. Certainly didn't back him 6 months ago when Liverpool got the best part of £250m value of players added to their squad for the 1st time for a full season - even if £125m was paid for last season in Keita and VVD. and this is when Utd were already clearly behind and needed serious strengthening and the big signings were a 2nd choice full back and 3rd choice gk....admittedly 50% was paid for by Coutinho going but even so , its in a completely different league in the backing sense to whats happened to JM
