You need to lose a defender and then depending on the formation you adopt the DMC also put at least one AMC in there.
Options 3-4-3/ 3-3-2-2/3-1-3-1-2/3-1-3-2-1
5-3-2 needs hard attacking with O/S trap on need faster defenders for that to work well.
Let me know which formation you fancy, we can go from there, was the first game home or away? CL I assume.
