This game will surely say that Bayern Munich really is champion material as if they are worthy of this season's championship, I really like to make a bet for that but that would be a game that will be pretty hard to predict, and as you said Bayern Munich would badly need this win if they don't want Thomas Tuchel to be stressed and have a heart attack as he wants to leave Bayern Munich because the club is stressing him out so badly that is why he just wants to quit Bayern Munich and go with Barcelona maybe to take a break,
The problem hasn't been in the last seasons, but the teams that had the chance to win the title but did not. Bayern is always champion material as you call it, but they have had some seasons where they struggled. The issue is that there is no team to fill the gap then and take the opportunity, but this time it might finally be different.
But I don't to be too optimistic too early. Last season I thought that Dortmund could win the title and then the end of the season turned into a horror show for every Bundesliga fan who wanted to see someone else win the title finally.
