this will be a rambling post, so bros bear with me, paiseh...
let me start by stating that in terms of tactics/strategy, mourinho (& co) was a B when at man u, while OGS (& co) has been a D. no doubt, mourinho was an A when at his peak (porto, chelsea, inter), u see the way his players go about the games, clinical, surgical, professional and well-drilled. so what happened at man u? my theory is that while the squad was well drilled, he wasn't able to motivate and bring the best out of some players towards the end and the environment became toxic, his methods don't work anymore so he had to go. in came OGS, as caretaker role, to change the mood and morale. by doing so, man u went on an incredible run to win 14 of the 19 matches during OGS interim period. basically OGS reaped the benefits of mourinho's work and everybody got giddy and he was made permanent manager
i believe this high lasted until the 20/21 season, as OGS&co continued to use mourinho's tactics so as not to rock the boat too much and also slowly introduced their tactics/strategies. we got to watch man u score a lightning quick counterattack goal in one match and frustratingly clueless in another. the problems have been there for a long time now but the coaching team cannot solve them after 3 years? this tells me that the coaching team are weak in tactics/strategy (weaker than mourinho's staff by a big margin). the current situation is similar to that of moyes' term, moyes brought in his own guys and tried to implement his philosophy/ideas, but results didn't go his way. seems like this season a switch turned off in the players and they can't seem to play to instructions, if there are any; looks like the players lost faith in OGS&co and can't be bothered anymore, seems like time is up for OGS&co
what next?
the new manager: if OGS is let go, who to bring in? i think the next candidate has to be a top tactician, disciplinarian and motivator, same for his coaching team as they are there to execute his philosophy. the new manager must also bring in a scout to scout the opposition thoroughly so that a plan can be formulated accordingly
the squad: needs another overhaul and clear-out. underperforming players who are on fat contracts - out. players who are slow - out. players who have low work rate - out. players who are often outmuscled - out. players who lack the correct mentality/attitude towards football profession - out.
ownership: must change hands but won't happen, the glazers won't sell unless there is a handsome profit to be made. who has that kind of money? russian oligarch? oil rich sheik? billionaire chinese businessman?
