Thomas Tuchel is right, but I don't expect them to make it to the semi-finals this season even though Bayern Munich are in a relatively easy group. Bayern Munich and Manchester United are two teams that have a big chance of qualifying for the round of 16, but I don't think they should underestimate the strength of the other team. It's a 90-minute match where it's always possible to have a surprise result, so I hope Tuchel doesn't have to talk too much about his good chances.
Dortmund did not have easy opponents because they were in the same group as PSG, Milan and Newcastle. Dortmund can be expected to be the one to lock in a ticket to the round of 16, but they have to work hard to take as many points as possible from a team that may be better than them.
