Honestly if Amorim’s departure will bring about the change then it should happen but I feel he should be given more time at least a summer transfer window to see how efficient he can be with it. Who knows what he can do with the summer transfer window ahead. This season is almost over with few games left to play, the focus now is to escape relegation and get a fresh start next season.
What makes us to feel unsatisfied is that Man United board looked like too hurry changing Ruud van Nistelrooy with Amorim. Now, van Nistelrooy is the coach of Leicester City. It is impossible to bring back him to manage Man United anymore. So, we have no another option, it is no problem to keep Amorim for another season. Sure, he should get a second chance to improve Man United performance. In the next transfer window, Amorim can buy some players that can be suitable with his tactics. But it should be the last chance for Amorim to show his quality in the next season. If he fails again, he deserves to be sacked.
