In a conference call for UFC 202, McGregor says he will beat Diaz in the second round.
I know I said I was going to stop the guy in the first round (at UFC 196) but if I really look at it I thought he has a solid chin, he’s durable, he’s very experienced. He has the size and the weight on me and I think that was the wrong thing to go in expecting the first round (finish). And I did go out to KO him in the first round, nobody can say that (I didn’t). I marched forward and backed him up against the fence and teed off on his head. I did what I said I would do. But respect to him. He stuck it out and he was durable, he was experienced. He weathered the storm. I’m still going to march forward, I’m still going to press him, I’m still going to bust him. There’s just going to be a lot more in my tank. I’m going to be a lot more prepared for a man that can stay in there with me. But even still, I struggle to give him past round three. If I was to make a prediction which I will right now, I believe I will repay the favour and KO him inside the second round.
