cup final advie

Hey guys playing in the cup final today, were both level 11, i´m a 74.9, he´s a 81, 8 of his players are world class, and the other 3 are superstar, he plays a 4-3(n)-1-2, can anyone give me any advice as how to play against this guy without getting a thrashing, do i play defensive, stick to normal, play normal tackles or go hard and maybe risk giving anyway a few free kicks, do i play wingers and flank attacks, and what about counter attacks, many thanks for your views, wish me luck.
