Being always two different championships, I would wait to speak too early, they certainly can't do it, but remember that it is always Borussia Dortmund, it's true they will play with a team like Sporting that is currently before, but I'm sorry I have a soft spot for them , even if they are not favored I will cheer for them
In the Champions League all teams will take advantage of any moment to be able to win and Sporting will also do that at home to have a chance to qualify for the next round even though Sporting does not know that Dortmund's condition is currently not good. But as the host in the play-off match, Sporting will do everything they can not to lose by targeting a win even though not with a higher aggregate goal. However, Sporting must be really wary of Dortmund in that match because Dortmund could change for the better in that match even though their current condition is still not good.
