Definitely. With Benitez it wasn’t even really a split, the people that were “behind” him only tolerated him because there was little else to do, as soon as things started to go wrong everyone just jumped over to the “out” side. With Martinez it would be actual bedlam among the fanbase, there is no universe in which that appointment works, it would completely end the club as we know it.
Which is why he needs a club job somewhere else, after the World Cup pronto, as you wouldn`t put it past a misty eyed Kenwright, talking him up to the idiot Moshiri.
