Sorry to say that, but i really think that the only man that can put Aldo in trouble is Pettis.
Mendes? Will be in the losing end just like Lamas.
The reason? NO ONE can really stop the favorite combo of Aldo: feint a kick. -> the other fighter becomes worried about the low kick and lift his legs to check. -> get punched in the face for trying to check the kicks. -> get punched a second time for trying to check Aldo kicks. -> The other fighter covers the head more with the hands, worried now about the punches. -> Get low kicked to hell.
And as a amazing fighter that God Aldo is, he has (or have.. i don't know) variations of the same thing, just like that: Feint a jab by going foward and dropping his weight. -> The other fighter cover the head another time. -> get low kicked to the doom. -> Lift the leg, trying to check a possible second kick. -> Get Left Hooked in the face.
