Hi guys, any advice to play against 4-5-1V while I'm down by 1 in the first leg of Championship and the second is coming tonight?

Our rating are almost the same,
in the first game I played with 3-2-2-2-1, got counter by his ST (4-5-1V) at the last moment, as checked, his best player is the ST, not sure about whether i should be attacking or defensive for the coming game,

Thanks.
