Country: England
Tbf me and a few others were talking about how LvG was putting a good template in place, they were absolutely dreadful in terms of recruitment but by the end of his time there he had brought in Martial, Rashford and at this stage Lingard was looking quite promising. Herrera ended up being a valuable asset for Mourinho, same with Fellaini who was in good form during United's 16 FA Cup run. Smalling was improving and was United's best defender while Mourinho was there. Rooney was pretty decent in a deeper role to an extent that Hodgson played him there for England (albeit England had a disastrous Euros). He converted Young and Valencia into fairly decent full-backs.
Their problem is similar to ours tho, they end up replacing him with a manager who had a completely different philosophy so turn down what LvG had built in his last few months. You could argue that Ole probably would've been better off taking over from someone like LvG who would've focused more on youth and would've had a structure in place as opposed to a Mourinho guy who's all about the present, a guy who'd buy a 34 year old for one year if it meant getting a title.
He was going to retire after the 3rd season regardless, he made that clear in his very first press-conference that this was his final hurrah but was sacked at the end of his second.
From a United stand-point he needed to be replaced regardless. We just backed the wrong man, City brought in Pep and United were almost pressured into bringing Mourinho in. It was poor from Woodward. Although, there were some benefits from Mourinho's spell too, he just wasn't right in the end.
Looking at Ole right now, he might not be perfect but I think the benefits outweigh the negatives with him for the time being, there's a lot of positives in terms off-the field recruitment, coaching, youth recruitment, club atmosphere and development but the biggest factor we need to see improve is on the pitch results. Even if Ole was to go at some point I think it's crucial that he stays involved with the club to some degree.
