I don't know, my feeling is rather that Ten Hag adapted his system toonmuch tonthe expectations with all the "we want tonbecome.the best transition team in the world" stuff. He didn't achieve what he achieved with Ajax playing transition football. If the club wanted that, they could have sticksd with Rangnick or signed a coach who actually stands ford this philosophy, say Roger Schmidt, Marco Rose or Hasenhüttl or something like this.
One reason for Ten Hag adapting is that he tried to keep what was working, I guess. The best players at United over the last years were Bruno and Rashford. But I'm not sure their play style is suitable for the very top teams at all as they play very risky and wasteful. It may lead to them having excellent statistics when in form but the team itself would probably score more (and concede less) when they played more grounded. Meanwhile, you see that players like Antony and Sancho who like to go for the simple option and play more patiently struggle to make an impact. While I'm sure this has much to do with them being out of form (when not suspended, that is), it's only natural that in a team that consists of "patient" and "impatient" players, the impatient ones will stand out more as they go for the risky option and finish off a passing sequence earlier than the patient players would. Hence the "all he does is passing it back, he never challenges his full back or makes something happen" criticism directed at Sancho and Antony.
Whatever you want to do, you should do it with consequence. If you want to play transition football, build a team consisting of players who excel at it. But then you should sign the players for it as well. I don't think a transition can challenge City, Liverpool or Arsenal over the course of 38 games but iif the club insists on the "United way", then fine.
