Amorim needs to make a change when it comes to the kind of formation he has been using that hasn't been productive... What is stopping him from using a 4-3-3 formation? Is it the board?
He can relate better with what he's doing or using but as someone who wants something good to always happen for his team to move forward and to progress, he had to change his pattern and try something different, that's why Pep Guardiola is better than many coaches in the EPL no matter how poor his team performs he's still the best.
The management of the Red Devils can't interfere with the formation of the manager, they can only say they don't want a certain player in their club, not with the strategy of the manager, if they do then they as the owners only want the down fall of the club and that's where you see the fans showing their anger, there's still time to make the club great again.
Amorim tactics are not working because if they are working the effectiveness would have shown in there performance so this shows that is effort is not impactful at all because for seasons now the club have gone from bad to worst. And pep is good and have set to a good record for him self even if last season was tough for us but I believe that this season is going to be different. Because even the whole divorce of a thing most have affected him. Amorim seriously needs to work on the pattern he as adopted because it is not working for thr club he needs to do better because the Club is already losing everything. And the management careless if not they would have taken a better action on improving the club.
