How to beat a strange 4-3W-1-2?

Hi guys, I've a Cup SF return match at home after having won the 1st away match for 3-0.
Me and the opponent have similar quality.
Before the 1st match I saw he used a 4-3W-1-2 with the only MC put in central-right position, as this:

GK
DR DC DC DL
MR MC ML
AMC
ST ST

He had maybe some not available players and he put a 4-2MC-1MR-1AMC-2ST formation wich I countered very well with 4-1-2-1-2 narrow diamond normal/defensive mentality, own half, normal/hard tackling, mixed passing and counter
Now for the return match he is put again that strange 4-3W-1-2 with the MC not in central position but in central-right position. It can be considered as a classic 4-3W-1-2? I was thinking of playing again with the narrow diamond.
Give me some tips.

4141 can be good too

meanwhile I faced him again with narrow diamond, he didn't watch the match so I had a good ball possession bonus playing at home and I beat him surprisingly easy 4-0, so I qualified for my first Cup final :)
