No choice has been made yet.
Benitez was a ridiculous appointment, we all knew that at the time (some tried to pretend it wasn't, I get that) Pereira has done nothing to warrant consideration.
It could work out OK, who knows, personally I think some managers just settle in well at certain clubs but if the issue is fans not being placated then it may be an idea for them to read the room a bit at least. Appointing a manager when its fairly obvious what the backlash would be is just madness.
There is a big difference between a fan not wanting a manager and being willing to give them a chance.
