84% at the end of the season? Dude, do you train your players at all? It is very low by any standards.

I don't see the possibility to win this on counter-attacks. The opponent will play defensively on counter-attacks. I'd play normal, maximum possession (Short passes probably), through the middle. DMC is obligatory here, so 3n-dmc in defense with ML/R; or 3w-dmc without. Man-to-man should help against counter-attacks.
3n-1-4-1-1 or 3n-1-3w-2n-1, something like this. Watch your flanks though, spread your defenders or switch to 4-dmc if he goes through (check "shots on target" in statistics).
