It’s tough to think of Aldo as a possible opponent because like McGregor said, it took him just 13 seconds to take the guy out. There are however, legions of Brazilian fans and Jose Aldo fans who think McGregor got lucky and landed a one-in-a-million type of hail mary punch that Aldo just wasn’t prepared for.
It would have been different if say for instance McGregor would have taken a round or two to establish his dominance over Aldo. So the fans are right in saying lightning may not strike twice for McGregor should they meet again.
Furthermore, after McGregor’s loss to Diaz at UFC 196, his aura of invincibility is somewhat diminished and I’m sure Aldo is chomping at the bits to get this one back.
