My view on that 'United manager roundabout' from Twitter:
Apart from Moyes who was sacked in his first and only season, both LvG and Mourinho got signings. In 2014 Van Gaal got Shaw, Herrera, Rojo, Blind, Di Maria and Falcao on loan. Next summer as a result/award of an ok/satisfying season Memphis Depay, Schweini, Schneiderlin, Darmian and Martial on deadline day. He still managed to finish 5th in a season where all the top teams were poor. If it wasn't for Rashford (who he gave a chance only because all the other attackers were injured) we probably wouldn't won Fa Cup.
Mourinho was able to sign Bailly, Mkhitaryan, Ibra and Pogba in his first summer, followed with Lukaku, Matić and Lindelof next summer and finally Sanchez in the January transfer window. We finished that season strong league wise but Sevilla defeat (more the way we got dominated in both games) was a worrying sign for most of us and for the board as well it seems. We still signed Fred in the summer and the club just wouldn't sign Jose another CB as he got 2 in 2 summers before, which in my view was only logical with the way he was behaving that whole summer.
Even though I am not a biggest fan of Ed Woodward and co, we're acting here as if the club hasn't been spending lots of money ever since 2014.
Ole got Maguire, AWB, Bruno signings right it seems, Dan James also could be an ok option for squad depth. Even with Covid making it harder to spend, I still believe board will back Ole with few signings this summer. If they don't then it's all on them when/if we regress again next season.
