My analysis of the situation:
1. Tuchel (who I never liked - putting it mildly) keeps Muller out of games where they need pressing and press-breaking help, I think for his own ego. It could also be from the bosses, who want to get Chupo-Moting off the books and feel he should play more.
2. The back line would be fine if there were not so may injuries, especially the young up and comer from the juniors who was promoted and was immediately injured, and if they hadn't shipped off what's his name to Leverkusen for the season.
3. I'm more worried about not playing Champion's Leage football next year than I am winning the Bundesliga.
4. I said it above, but Tuchel while being a genius, is a stubborn prick the players can't stand and has been booted everywhere he's been (see Bayern player's council). With the recent form, expect the same to happen, hopefully at mid-season break.
5. Regarding midfielders, where's Sabitzer when you need him?
6. Expect an arse-ripping loss to ManU. Even without that, I doubt Uli and company will keep him after January 1.
Sorry if I offended, I'm pissed and disappointed at the level of play, notwithstanding where they are in the standings today.
