You have a decent center and defensive players. The classical formation like 4 5 1, 5 4 1, 3 5 2, 4 1 3N 2 , 4 4 2 will suit your players.

Be little careful of wing based attack. Try to play with normal and defensive mentality.

As per the formation you have as of now, better change it to 3 5 2 flat and put red arrows on ML, MR and Blue on center MC and it will change your attack to 3 5 2 v. So it will give you more variety and flexibility.

Best of luck!
