I believe PSG is an overall better team than Dortmund and should easily win over them.
For starters it's a miracle that Dortmund are actually here because they looked like the weakest team in their group and when it came to the quarter finals I really don't understand what happened to Athletico Madrid who were in a winning position and let the game go to BVB who really turned up the heat on them to qualify...Btw, Dortmund have gotten better as the competition progresses but unfortunately we all know PSG has more firepower and this might be the end of the road for them as that Mbappe lead team is playing some good football!!
PSG are the top team in Ligue 1, they has defeated Barcelona in the quaterfinals, which is a second team on La Liga. While Dortmund is the 5th team on Bundesliga who defeated Atletico Madrid which is the 4th team in La liga. Every stats shows Dortmund have an easier path to semifinals.
No no no no, please tell me you just didn't do that...If you are gambling person and are going to use this formula to find your winner , I think you might lose more money than you expect because football is not an equation and I would advise you go for form or history of the fixture. Otherwise Dortmund were lucky to reach this far because if we ask anybody to explain how BAYERN got here very few can explain if we looked at their form but history of the competition shows they are a beast...
The Munich vs Real Madrid would be the ultimate battle. The winner of this high stake match would be the favorite for the championship title.
Safe bet to avoid headaches, go for the history holders of the competition... Real Madrid and thank me later
