#3 Nate Diaz

Despite McGregor defeating Nate Diaz in their August 2016 rematch following his initial loss to the controversial fighter 5 months before, the bad blood between the two has never truly gone away. The fact that the second fight was so close has always meant that a trilogy match would probably work as a pay-per-view draw, but until recently, McGregor – probably distracted by his feud with Khabib Nurmagomedov – has remained pretty quiet on the issue.
That all changed last weekend, though, when Anderson Silva called for a rematch with former foe Nick Diaz at UFC 237, which is scheduled for Curitiba, Brazil, in May 2019. Almost immediately, ‘The Notorious One’ then took to Twitter, suggesting that if the UFC could get the Silva/Diaz fight signed, he’d be willing to fight Nate Diaz on the same card.

The likelihood of this actually happening at UFC 237 seems pretty slim – the build to a McGregor/Diaz trilogy fight would probably need more than a couple of months and the UFC has already suggested that Amanda Nunes vs. Holly Holm will headline that card – but later in 2019? It’s definitely a possibility, particularly if the UFC doesn’t want McGregor to rematch Khabib right away.
