Long flank passing vs your 2 flank defenders.. low, defensive, counterattack. Your stats don't look like an advantage. If I play 41212 ND and can't hold 65% possession against a strong team, there is a problem. I look for 70% possession, 25+ shots, 87%+ pass completion with that tactic against a good team. Wrong match up in this case.

Keep trying, which isn't what you want hear. Pushing harder with your attack is... Often... not the answer.
