The formation he's using is the well known 4-5-1 V Style which destroys most formation.

According to my experiment, 3N-2(DML/DMR)-3N-2 (with good defender and striker) works well, I beat a person with that formation by 2-0 despite he has more power (Overall 17 vs 20/21).
4-3N-3 is also said to have been able to defeat 4-5-1 V Style according to what I've heard.

The approach I recommend is Defending/Normal w/ Counterattack, Mixed (3N-2-3N-2)/ Through Middle (4-3N-3), Mixed Passing, Hard Tackling, Own Side Pressing
