I haven't watched enough of either fighter to make an educated prediction but I think I'll have to go with McGregor.
I haven't seen enough of Aldo having an ability to handle an outside fighter like McGregor or seen enough of Aldo having the foot speed to close the distance. At 5'7 and 5'9 both fighters are midgets (no offence @
White_Lie; and @
Grunta;
) so both have relatively good foot speed but not extreme for their weight division.
BUT, I suspect it'll make it out of the first round.
McGregor by stoppage round 2 or 3.
(Come on @
Bazza20; NFI is not a prediction. You too @
C_T: and anyone else )
