In addition to playing with the strategy of utilizing fast counterattacks, Monterry should also be able to take advantage of what can make Dortmund's game open.
In general, it can be said that Dortmund played defensively and Monterrey played offensively.
If you want to feel how well the two teams play with a good strategy shown, then the answer is the Real Madrid vs Juventus match.
Real Madrid played a very good game pattern in my opinion because of the emphasis on the wings. Juventus must admit Real Madrid played quite well and Juventus' game was different against Man City.
Monterrey was just not good at completing the attack they built. In contrast to Dortmund who played more effectively and were able to complete their attacks well. Maybe if Monterrey had managed to play better in attack while maintaining good defense then maybe Dortmund would have lost that match. But yeah Dortmund deserved to win in the end.
Real Madrid played well. But Real Madrid is still not effective in completing attacks. There are still many missed opportunities. But I think with Xabi we will see a great Real Madrid again. And I am happy that Real Madrid has not experienced any decline in performance at all. In fact, I see positive improvements in their back line.
