Mate, at this time we ought not to be mentioning Sir Alex Ferguson if other coaches succeeded. Remember after Sir Fergie, we had;
Moyes;
Mourinho;
Van Gaal;
Ragnick,
Ole and now
Erik Ten Hang.
If the above mentioned names were successful, we shouldn't be mentioning Sir Fagie at this time. I am not in anyway justifying Erik10 poor performance, but I believe he didn't have the quality of players needed to excel this season. His first season in Manchester United, he ended 3rd because he had good players. He was able to stop City in the FA CUP finals because most of his players returned from injuries.
The list is just long mate, if you look at this mangers they were all world class before joining Manchester United per Ole who actually did well. One common thing about them all is the fact that they all had a better first full season mangers like Van Gaal, Mourinho and Ole were even runner ups in the premier in their first full season but they fell apart in the second season reason been that they were not back properly. Rival fans will argue that every summer, Manchester United spends more or close to in Europe top five leagues, so coaches Shouldn’t be using the lack or backing as excuse but I tell them that it is not about spending but was the money spent well on the players the manager requested for? No so it affected them.
For Erik Ten Hag should be given more time, so that he can actually be able to implement is pattern. Even the great Sir Alex Ferguson spent three season before he got his first trophy too at the club
