The last time Dortmund reached the final of the UCL was more than ten years ago. Dortmund was returning but failed to acquire the trophy because Real Madrid had stopped them from doing it last season. Dortmund was not fortunate to have Madrid as their opponent.
We know how big the gap is between Madrid and Dortmund. I was rooting for Madrid, and they have won the UCL 15 times. The quality of the players says it all.
But again, I wouldn't describe Dortmund as a small team. Though not as popular as Madrid, Dortmund's name was quite well known.
Real Madrid is elite team, they fight harder than any other oppositions and they grab every amount to push forward and obtaining crucial winning in major tournaments. Borrusia Dortmund is an elite club, everyone knows about the club's status because the management have slide into selling their key players for generating huge profits, they no longer work harder towards winning titles, it have become a routine for the club. We've come to understand that Dortmund don't fight for titles but for recognition which is their current happening.
