Of course it is possible that Amorim will bring Man united back to glory like in the era of Sir Alex Ferguson where Man united appeared very impressive and won many trophies. but of course Amorim will need a long time to be able to make Man united good like in the era of Sir Alex. but yes I hope Amorim can prove to everyone that he is a good and professional coach.
That's a lot of ifs. I remember hearing the same thing about ETH in his early days. At the end of the day, on-field performance needs to get better. They also need to fix their recruitment since most issues come from that. I'd like to see them do what Chelsea did if they're brave enough for that, which is hiring young players with potential and a good mentality to reduce the cost to run the club for a while. Most revolutions of big clubs start from the top, so they should fix that quickly. CMIIW.
