Tuchel has nothing to lose from now on. This is making things really difficult for bettors to make a decision upon betting on Bayern Munich in the remaining games.

But I still expect to see Tuchel doing his best. Bayern Munich should normally be able to eliminate Lazio by the second leg at Allianz Arena. But will I bet on them to win? I don't have big intentions about it for now.

Maybe I might try my luck with both teams to score. While Bayern Munich are vulnerable recently Lazio might score a goal here as well to make things harder for their opponent. It has 2.00 odds which is very tempting.
That is the downside of firing a coach without firing him. Tuchel knows that he is fired now, so why would he try to win? He could just test stuff out that he wanted to but feared that it would backfire. Now that he knows he will be fired anyway, and he has only a few games left, he could just do whatever he wants to do and that should help him a lot.
I believe that the best thing to do in this case would be actually firing him and get someone else who needs to win, doesn't have to be a big name, just the staff member in that club would be fine, pick one of the coaches and just put them in charge. If they let Tuchel have his way until the end of the season, then we are not going to really end up with anything good at all.
