The only reason Man United management appointed Amorim to replace Ten Hag was because his performance with Sporting was very satisfactory, the same thing was also done by Man United when they brought in Ten Hag, at that time he was a successful coach with Ajax Amsterdam. It should be underlined that the EPL atmosphere is very different from other leagues, Amorim needs to adapt to the EPL hard and fast style of play. Now Amorim is carrying a big responsibility, he is expected to raise Man United status back to being a respected club like when Alex Ferguson was still in charge. I'm not sure he can do it anytime soon because the competition in the EPL is very competitive.
