The only managers IMO opinion who could last more Than 2 years, is probably a Galtier or potter. The rest IE Rafael as you say the fan base will be against him from day one, he will have to hit the ground running.
Nuno will b a disaster appointment if he gets his way on transfer Witt Mendes. A ream full of Portuguese players. It will be another koeman, gone it 2 years and a squad that needs ripping up. The fans will not accept he’s negative boring defensive football.
Dunc is not up to job IMO.
Howe, can’t even be bothered saying anything about him.
I do think Rafael will attract better players. And will probably let brands buy a few youngsters why he targets one/two ready made players. I don’t think he will last that long, but the best of a bad bunch unfortunately
