Cup Game...5-3w-2 counter??

I'm facing this guy who is 2 levels higher than me...so obviously he has higher quality than me(112%,mine is 104%)....but the thing is....I think he is using defensive or hard defending tactics as his team will be 72% in his league and he is using 5 defenders...and I don't think he will be changing the tactics(as he used the same in previous 2 cup matches)...SO, HOW CAN I GET PAST HIS 5 DEFENDERS with his DEFENSIVE or hard defending tactics???

His formation is 5-3w-2....which formation or tactics should i use???...I have players with 100% quality in all positions.

His formation:. GK
