Opinions, what formation should i use with my current players?

[markherb]

Ive been playing for a couple of weeks but need help on formations. What should i use to beat my next opponent and what do I need to strengthen in my team?

I lost to my opponent in the Champions League when he played 4-4-2. Despite having better players and beating him in all stats, he beat me 1 - 0 at his home ground. I used the line-up shown in the pic, is it luck or is my formation terrible?

I think he will use this bellow in our return game and defend and counter attack me how do i beat that?
-----------ST--------
------------------------
ML-----MC-----MC----MR
-----------DMC----------
-DL-----DC----DC-----DR

Thanks in advance, sorry for all the silly questions
