Dude, that man is 74 years old and you want him to crawl back to his old office. It will be fine if he do save MU from the mud, but what if he fail too, that will ruin his managing legacy, people will not see Ferguson as a legend anymore. He is living really well in retire, watching football matches and sometimes criticize or praise some players, but don't ever come out from retirement because even the best can't help Man United at this point.
Yeah even Sir Alex needed at least 3 seasons to win his first trophy for Man United, I know it is not that easy to (re)build Man United. But isnt it sad for him by just watching Man United lost almost every game in Old Trafford? Scholes once backed from his retirement and helped Man United for one season, so why not for Sir Alex?
When Scholes backed from his retirement he is not played so much, so he is not give so his contribution to manchester united that season.
And for Sir Alex Back, I don't think that is a good way. He is too old to manage the club. I know the coach is not running on the field but to make Manchester united out of this situation, he is not the man.
He indeed didnt play that much, but are you sure he didnt give contribution for Man United at that time? I think scoring 5 goals from 33 appearances after coming out of retirement is more than "just a contribution". He really raised his teammates moral on the pitch and played well in midfield area. Some media also said that he became the reason why Pogba leaved Man United in 2012. And back to Sir Alex, yeah I dont expect him to run or shout on the field, he just could become strategy planner and sits on the bench, so his assistants will do the rest. The other way is just wait Mou patiently without blaming or judging him.
