I would play my MC deep for extra support for defence as you only play 3 defenders. And MCs usually play better defence than offence in this game anyway. I would place the MR as close to the center as possible without getting a penalty. I would play Hard attacking mix attack short passing (to minimise counters and loss of possession) because you have so many attackers so just kill whoever with your attack. I also like to play offside trap when I play very few defenders. AMC play a little deeper as well to help defend abit and push ball forward
