#2. Conor McGregor vs. Nate Diaz - UFC welterweight division
There may not be a bigger rivalry in UFC history than what we saw between Conor McGregor and Nate Diaz. The two superstars despised each other and the story was made all the more intriguing when Diaz upset the surging McGregor in their first fight by submitting him in the second round.
McGregor then made it his mission to get revenge against Diaz, securing a rematch right away. The two men put on another incredible battle that was very tight with one judge unable to separate the two. However, 'The Notorious' did get the revenge he sought, winning a majority decision the second time around.

Earlier this year, it did look as though we may witness a trilogy fight between these men. Unfortunately, it now seems as though Nate Diaz may be on his way out of the company and we still have no clear idea as to when Conor McGregor will return.
#1. Francis Ngannou vs. Stipe Miocic - UFC heavyweight division
Francis Ngannou has done an incredible job of transforming himself into the seemingly invincible powerhouse he is viewed today. He has done well to create this aura because when he first arrived in the title picture, Stipe Miocic proved he was not yet ready to be champion.
On that occasion, Miocic out-classed Ngannou, winning every round on the way to a unanimous decision victory. This loss slammed the brakes on the hype surrounding the fighter from Cameroon, who spent over three years getting himself back to the belt.
When he did, Miocic was once again waiting for him. The rematch showcased Ngannou's improvements as he looked great on the ground and eventually knocked out Miocic in the second round. What is to come for the new champion remains very unclear, whether it be in the UFC or elsewhere.
