Counter formation suggests 43N3. I've used 43N12 against 451V and I have to admit it suprised me positively. Since this formation is narrow by default, you could play with mixed passing (instead of through middle.) Since he is stronger, I would suggest normal mentality without red arrows, zonal marking, hard tackling. If your team doesn't create chances with short/mixed passing (lenght), try with long. Don't force nor counterattack neither offside trap. Good luck.
