That's some high level delusion if you think Phil Jones even has half the ability of Franz Beckenbauer (Oh Dear). It's not hard to believe if you take into consideration that they both have had managerial careers for many years yet have always played the same way. Look at Eddie Howe, had his team playing attacking football in lower divisions and now in prem despite not having much money to spend, while Mark Hughes had money at city/better players and that job went same as his previous one's, dull then got the sack and now is recycled by bottom half of Prem then gets the sack. Each manager has a style with which they are familiar with, Eddie Howe is familiar with attacking football and despite the budget he had/has, Bournemouth play good attacking football and Steve Bruce/Mark Hughes have always been comfortable with their style which is similar to Jose. Don't know why you seem to think they would all of a sudden play some great attacking football despite never ever attempting to play that way before in any of their previous manager jobs (btw attacking football isn't telling your players to go attack and expect magic but by having a plan on how to attack, which jose had no clue). Well Maybe the likes of Paul Ince and Redknapp
said United should get Bruce

Maybe that's why you fail to understand.
Being steeped in the United way means nothing if they have never tried to implement that in their other clubs, Ole despite his failure at Cardiff at least tried to implement his attacking play. Ole went back to Molde Fk and again Implemented his style of attacking football and Now at United, United play similar to the way Modle Fk play. which isn't by some "he's steeped in the United way" magic but by him implementing his style (attacking football) on his players.
It doesn't mean he will be successful here but its clear to see Ole has a clear idea of how his team should play despite the players he has had in previous clubs and now at United. United could lose the games vs big teams but the attacking intent will be there and it certainly won't be Jose/(Steve Bruce and Mark Hughes) style.
Managers don't all of a sudden go from Pragmatic style of play to Klopp/pep style football, this is not FIFA where they can go to custom tactics and change their styles. Look at Jose, he had attacking players from the go at United and bought more attacking players then got them to defend for 70+ mins in a match not against city or pool but against bottom half teams.
