Dude, what do you think of Dortmund next season? They lost in the final round this season and that should make their motivation even greater to avenge their failure. They have lost twice in the final, the first time against Bayern Munich and the last time against Real Madrid. Their efforts were very good to reach the final but their luck was less fortunate when they had to face a prestigious team full of history in the Champions League.
I think Dortmund is one of the underrated teams and maybe we should be wary of this team even though it is in a group filled with other strong opponents. If only next season they had to face strong teams again before the final round then they could definitely achieve it again like this season. So it's not surprising that even though they are less fortunate, at least their mentality should be appreciated.
