Yes they can be stoped

[Tactician]

The game made logic, I played defense and counter attack GK DL DC DC DE DMC DMC ML MC MR ST, the ST is my best player and was decise scoring most of the 5 goals, the other team tried two diferent tactics on both games but they couldn't do better, we were both active during the game.

What did the oppponent used as formation?

Yeah, 2 DMC in front of a back four is good for counter attacks if the remaining front players are fast enough and also can spread wide while still have a man in the middle, which means 2dmc, followed by a 3w-1 is good for that purpose.
