Conor McGregor believes he can beat Dustin Poirier easily at UFC 257. Even McGregor claims it will be easier to win over Khabib if he does a rematch.

"It will be an easy rematch for me this Sunday, but it is not the easiest rematch. When I fight Khabib it will be the easiest rematch. I can guarantee that," said McGregor.

while Poirier already has a plan to destroy McGregor. Poirier believes he can beat McGregor if he can fight for up to five rounds.

"At the end of the round, I was getting better. I'm sure McGregor will make adjustments. He is getting slower at the end of the round. I think the longer the fight, the better the advantage for me," said Poirier.
