Dortmund has starting their pre season tour yesterday that they had big win against Germany 5th division team Westfalia Rhynern with huge scores 7-0 and as people predicted they were too strong to their opponent that since the beginning of match Dortmund were playing very agressive and in the first half Dortmund were able to leading 3-0 and their statistics during the match also looks fantastic that Dortmund has 79% ball possession and 36 total of shots
I know Dortmund opponent is so weak so i am not surprised if they can able to win with big scores but this first match is good to restore their players fitness and Dortmund next match will be against another weak team Rot-Weiß Oberhausen on Wednesday that Dortmund at least will have 6 pre season matches before Bundesliga starting again and next month Dortmund will fight against Premier League Chelsea and Manchester United
Dortmund didn't have a hard game against this team and they're totally unknown, however, Drtmound and all other teams are in the training phase and they are mostly not ready for the games otherwise they could even win the game with better results. I think the thing Dortmund left do to for this season is to find a better replacement for Bellingham they sold to Real Madrid.
