Got an important game tomorrow... I will be playing away and the opponent is set up in this 4-2-3N-1 formation:

4 (DL DC DC DR)
2 (DMC DMC)
3 (MC MC MC)
1 (ST)

His rating is 14.2 while my rating is 17.5, I set my team formation as 3-4-1-2:

DC DC DC
ML MC MC MR
AMC
ST ST

His MC and ST are his stronger players but the rest are pretty average, I was wondering if my formation is appropriate for tmr's match. Also one last question is, I have a DL with aerial defender trait rated 20... should I swap him with a 16 rated DC and play him out of position at DC or keep the 16 rated player in his natural position?

Any input on the above would be appreciated! Thanks
