Thank you for your reply! The game was already over the time your answer has been postet but I actualy used the 451V formation and I won 2:0.So it was a good advice and good to know that DML&DMR can do some damage as well on the sides. Will take that information in the future into consideration.
Oh and btw: I hope you can understand me despite my rusty English skills.
Best,
