I can't see a single player in your squad I would put into my teams starting eleven ahead of anyone we have.
If Onana comes, I'd have him over a 37 year old, coming back from a leg break, Neuer. Similarly for the CBs, would prefer both United CBs to Bayerns. At LB you can argue Shaw and Davies, who was in and out of the team last season, are similar. At RB Bayern has a clear edge.
Midfield it's close, Kimmich and Casemiro are top players in their position, then you have a mix of Musiala, Goretzka, Muller competing for the last two positions against Mount, Bruno. Mount v Goretzka is close and I'd take Goretzka but Bruno v Musiala/Muller is a no brainer in terms of who is better right now. Musiala is incredibly talented and Muller is an all time great, but Bruno is better than them.
At the wing position Bayern definitely have much better depth with Gnabry, Sane, Mane, Coman but I would say Rashford is better than all of them, though after Rashford United don't have better players.
Striker, if it's between Woug and EMCM, I'd take Eric Maxim
Overall, like I said it's pretty close on a starting XI basis.
I'll keep pointing this out till the end of time: Van Persie did not turn United into title contenders. We already were. He came into a squad that scored 89 goals and got 89 points the previous season.
It's a very different scenario now, and very much similar to turning Spurs into title contenders.
True, that's a rewriting of history to say he turned us into title contenders, but you can't ignore that he really took us up to another level whereby we walked to the title.
