I guess Moyes tactics have something to do with they being a bit clueless on the pitch.
Also the situation of sacking Moyes isn't comparable with Chelsea/Madrid sackings. Chelsea sacked the manager for finishing in the second place. Mourinho come and won them two titles after half a century and then was sacked after a season without a trophy. Ancelotti came and won them the title (and the cup) after we completely dominated on three years and then he was sacked on the following season for finishing second. Madrid sacked Del Bosque on 2003 and Capello on 2007 for not being able to win UCL despite they won the title (Capello after 4 years, since the title of Del Bosque). That was absurd and lunacity.
Here, pretty much every United supporter was ok with us not winning the title for three years as long as we were competitive and we qualify for Champions. But being on the midtable team, nearer the relegation zone than the leader isn't great, isn't even good, isn't even mediocre. It's absurd and horrible. There must come a time when we realize what retarded decision we have made. From now on, it is all about damage limitation. Sacking Moyes IMO is the most logical decision to make and wanting to prove that we're better than others by sticking with him, will just make us look arrogant and it will be more difficult for his successor to recuperate. In the end of the day, the trophies are all that is counted, not how years we sticked with a manager.
In the last 10 years:
Barcelona has had 5 managers. During that time they have won 6 La Liga, 3 UCL and a shitload of other trophies. They will likely win the 7th La Liga in those years this year.
Bayern Munich has had 9 managers. During that time they have won 5 Bundesliga, 1 UCL and a shitload of other trophies. They will likely win another Bundesliga this year.
Point is, changing the manager isn't the worst thing you can make. Teams remain pretty succecful by doing it all the time. It is obviously great having the same manager for a lot of years but having that priority is absurd. Better is to choose a great manager. There aren't many of them who would left us just for the sake of it. I think it's more logical staying with the same manager for a long time, with medicore results just for the sake of it.
Would people here prefer that in the last 10 years to change 5 manages but to win let's say three Premier League titles and a UCL, or they would prefer to stay with the same manager for the next 10 years but our only trophy to be the fourth place trophy? I for myself would choose the first option every time. Even if that would make us look normal and won't make us feel better than the others who sack their managers all the time.
