I do not watch foreign football as much as I used to, but thanks for the compliment
I think he can get his teams to have more of a cutting edge with time but broadly if I'm not mistaken this is very much his style, and I think he has players already in his squad to implement this quite well, so that might explain the quick impact. He will likely find good use out of players like Havertz and even Werner who are intelligent and know how to use find pockets of space and exploit.
For what it's worth I rate Tuchel but I for some reason I didn't love him as a choice for United's role, probably too much burn from our LVG experience! But I prefer a more direct approach to our games as that's what I grew up associating Manchester United with. For that reason Ole's style actually suits us more, in my opinion. He might have us on the counter a bit too often but he is more direct and tries to hurt teams quicker.
What I wish Ole can learn more on compared to his counterparts (Tuchel, Klopp, Pep, to an extent Arteta all included) is improvement in team press. It's a bit of an art I think, and not just a "press high" and job done. There is likely an element of coaching for team pressing which Ole needs to implement better.
Chelsea look to press a lot better now under Tuchel, he's actually gotten the best out of Kante since what, Conte days. And collectively there is a systematic approach to how the team will win the ball back. I get that vibe with our rivals but not often enough with us. Part of that is tactical, for example I think Ole purposely leaves Rashford and one other high up the pitch without duties to track back as much, so that he's set up on a counter easier. At least thats how it looks. Some of it may be personnel too - for example Martial isn't one to press proactively.
