I like 4-2-3-1 much, but maybe give it a try?
4 defenders
2 defending midfielders (centres)
3 attacking midfielders
1 striker
The idea would be big defence, and also have a lot of attacking players there, most at the midfield.
So after their pressure attack, you could outnumber or at least have a decent change at the counter.
But you need a good striker then, that is technically and fast and finish his changes.
Think this would be the best for countering, as long some other players do their passes well.
