how to beat this defensive set-up ??

Wondering whats the best formation on beating this ? We're equal in terms of team quality but i've won 20 league games on the spin and want to do the 26 ! His team has 4 defenders, 3 DMC, 2 MC and 1 striker ! I'm guessing maybe down the flanks and starting with 3 DC's, so maybe 3DC, 1 DMC, 2MC, AMR, AMC & 2 ST. Any other suggestions plz ? Thanks

He has illegal formation(less than 4 players on opponent's half).u shud win easily

Thanks for pointing that out, didnt realise although it looked illegal. Hopefully not a ploy to throw me off, if it is i guess he'll go 5-1-3N-1, usually does against strong opponents so might set up to play against this !
