Although Dortmund did not play well in the home match, Dortmund played very well in the away match. And Dortmund's players were desperate to win the match. Dortmund's match strategy was good, the players were also very confident. So in the end, Dortmund was able to secure a 2-1 victory in the match. Dortmund's players took 17 shots in this match, out of which 8 shots were on target.
Dortmund will play against Barcelona in the quarter-finals of the Champions League. And it is almost impossible for Dortmund to win this match. Dortmund's performance is very irregular. I have not seen Dortmund play well against big teams. If Dortmund can somehow win against Barcelona, they are very lucky.
But if Dortmund's luck is still as great as last season, then Dortmund could surprise again by winning against Barcelona. But yeah it requires luck. Because without it Barcelona would really beat Dortmund badly. Moreover, Barcelona currently has sharpness in their attack line. Barcelona this season has been very productive in scoring goals. So the opposing team must really prepare a strong back line to be able to withstand every attack launched by Barcelona.
In the first leg of the quarter-finals, Barcelona even hosted. So Dortmund really has to be able to strengthen their defense. Because of course Barcelona will target scoring a lot of goals in the first leg. But Dortmund actually also has a pretty good level of back line. So I think it will still be a fierce match in the end.
You are right that Dortmund has a chance to win if they are lucky. Last season, Dortmund qualified for the Champions League final. However, Dortmund's performance was quite good last season and their opponents were also relatively weak. Also, Dortmund was very lucky.
However, this season, Dortmund is not as strong as last season. Dortmund's performance in the Bundesliga is very weak. Dortmund is not able to dominate and win matches in the Champions League either. However, it is true that luck is helping Dortmund a lot. So Hansi FLick must choose his match strategy very carefully. No mistake can be made in the match against Dortmund.
