Put a DMC on the bench in case he/game engine picks the AMC.
Make sure you start with 3 DC'S and DL/DR on the bench also.
If he does go 4-3-3 put red arrows on your MR & ML if you play five in the middle.
4-3-3 will attack you so don't get to carried away at the start, read the comments and see how and where his attacks are building from.
Then counter them if he's hitting long balls sit back. defensive, down both flanks, own half, tackling easy/normal, passing mixed zonal, no OS, force counter yes.
If you have a AMC play him instead of the centre MC he will be able to receive balls from your wide men and set up your strikers better.
