That is an illegal formation. He has less than 4 players in your half. If he does not change it, you get 80% possession.

4-4-2 and 3-5-1V should both work with the first system. Which is the best system depends on how he motivates his players (red/blue arrows). At both systems I suspect the other manager wants to play counters with his world class forward, take care there. If he motivates the MCs 3-5-1V is probably the better choice.
