How to beat 5-1-1-1-2? Cup - Last16

[Bubba]

long ball is not a good idea. long passing is for jumping the midfield line, not the defensive line.

It should be, but if so there's no way to jump a 5-men-defending line 'cause they "double" every zone in front of own goal.
I think it could be more dangerous keep free the short opponent's "V" (AMC-ST's) then the defenders. Sure, they could come up and score but they have to leave the defending line. To get this he has to play counterattack in defensive. 4-3-3 gives stability on midfiled (3 men Vs 1!) and has a kind of coverage on back. With 5 defenders you should deploy at least 2/3 strikers. If you're afraid of his attack you could move back an MC (4-1-2-3), your wings don't need to be covered.
My opinion, i would have played so....
