First, check the form of his players. Just because they have greater quality, doesn't mean they're better players. If several players (especially defenders) have poor form chase the game.
3n-1-4-2/3n-5-2 V are probably your best counters here.
attacking/down the flanks/whole pitch/hard/short/zonal - no counters/offsides (optional) or
normal/down the flanks/own half/hard/mixed/zonal - no counters/offsides (optional)
If watching the match, i'd probably start with the normal setup, then as the games progresses switch to the more offensive setup if in need of a goal.
However, if you feel the need to play defensively.
4-5-1V/4-1-4-1. Hard defending/down the flanks/own half/hard/long/zonal - force counters/no offsides.
