If i'm not mistaken, his formation is illegal. He got only 2 defenders, he has 4 players on the right and 4 players on the left (by the rules, 2 is the biggest number from players on each side of the pitch). In order to defend yourself, i would try 5-2(DML/DMR)-2(MC)-1, focusing on the middle. Considering he chose this formation on purpose, he'll probably be playing in counter attack (as his illegal formation will give him 20% of ball possession - or something close to that), so you should play carefully, without opening him space for countering (this is why i would go with a formation with a DR and a DMR - so you can try to defend from the 4 guys he has each side).
