DL-DC-DC-DR
MC-MC
AML-AMC-AMR
ST

I don't remember playing against this formation before and this is a very important match, as the guy is two points in front of me, and it's an away match. He has a very young team, with an average of 19.6 and all of his players on the field are six stars, except for one defender. However, he's using a player with DML-ML as a DL, and a DC as a DR.

Which formation is appropriate to get a clean, comfortable win? My team is a bit weaker when it comes to average stars.
