Honestly? I think its is 100% the worst appointment the club could make. Its not even because of him as such.
I do not think he is a relevant manager in 2021 but that's by the by. A manager, any manager, needs to be given a chance to succeed and he absolutely will not be given that chance. This would also apply to Moyes and Martinez as they were linked. Their cards are already marked. I don't think that's a particularily outlandish thing to say either?
As for the "no marks". Every manager has to build up a career. The likes of Potter, Howe, Nuno etc may have worked, we will never know. All of them have ability but all of them come with a risk, every manager does really but honestly Benitez will be doomed from the get go. He has got absolutely no chance.
He wont care mate.
