Guy's "Final Fight" combo

I’ve been trying to use Guy and I’ve noticed that most of his damaging combos stem from his “final fight” combo. My question is… does anyone have any advice as to setting up the FF combo? It seems like when i get inside to do the combo most people just crouch down immediately upon waking or at any hint of an attack. Thus basically making it hard to even get the combo to connect. Is there any way to link into this combo if your enemy is constantly crouching?? Better yet is it even a smart move to attempt to link into the ff combo if the opponent is crouching. lol i hope that makes sense and any help would be greatly appreciated!

No, because the :lp: wiffs. However, you can preform the target combo (:mp:, :hp:) on crouching opponents and hit confirm it with cr.:lp:.
