How to beat this weird formation

[lunentianutto]

My team is on par with him.
My 3 best players are 2 STs and MC.
His best plaers are LB and DMR
He lost to this formation 5-2 away before but I played him away so I don't know whether it would affect or not.


I just want to score as much as possible and I don't care about the goal difference. (To climb U23 leaderboard)
PS. all my player are U23s.
Thank you in advance.
