Joe Rogan tells Conor McGregor the one area he needs to improve to beat Nate Diaz

It looks pretty certain that Conor McGregor and Nate Diaz will face off in a rematch at UFC 200.

The California fighter got the better of The Notorious at UFC 196 earlier this month in a fight staged at 170lbs. While it's not clear what weight the re-match may be fought at, Joe Rogan feels that the Irishman has a lot of improving to do if he is to achieve victory. Speaking on his MMA podcast, The Joe Rogan Experience the UFC commentator admits that he was worried about the strength of Nate Diaz's jiu-jitsu skills in the fight and the fact that Joseph Duffy had previously submitted Conor McGregor. Rogan feels that if the Irishman is to have any hope of success, his ground game will need to be improved hugely: "A guy like Conor, if you've been tapped before, especially by a guy like Joe Duffy with an arm triangle, if you get caught like that, you got a lot to learn, and I don't know if you've learned it," Rogan said. "You got to be obsessed with jiu-jitsu, you gotta be in there everyday and I don't think it was that, it was more movement and striking and all that stuff and I know he was doing some jiu-jitsu but it's not like the primary focus so I felt that's a big deep end jump." Rogan feels the fact that Diaz knows McGregor's ground game is not as highly skilled as the Stockton native, will force the Irishman to improve. "Now that [McGregor] didn't, and that Nate knows he didn't and they are going into the second fight, and Nate is going to have a full training camp, ooh, good luck." We can't wait.
