It’s been a while since Conor McGregor has fought, but he will step back into the UFC cage on Saturday night to face the undefeated Khabib Nurmagomedov for the Lightweight championship (which technically isn’t his anymore, but is a title he also never lost). Naturally, McGregor is making the media rounds this week to promote the fight. He appeared on the MMA Show with Ariel Helwani on Monday, and plenty to say about his fighting future. Most notably, he mentioned wanting a boxing rematch against Floyd Mayweather at some point.

“I would like to box him again,” McGregor said of Mayweather. The two engaged in an entertaining “superfight” last August, losing via referee stoppage in the 10th round. The negotiations and promotion of that fight also kept McGregor out of the UFC for a long time, forcing the company to strip him of both championship belts he held due to inactivity.

Mayweather is apparently busy planning a rematch with Manny Pacquiao, but fight fans seem lukewarm about that matchup after a boring first fight between the two legends.

McGregor also talked about a potential MMA superfight with Georges St-Pierre, saying he would be open to the challenge. However, since GSP doesn’t have a title for McGregor to compete for, it’s not a high priority. St-Pierre has already spoken about wanting to fight the winner of McGregor and Khabib, although it’s unclear if the former Welterweight and Middleweight champ can cut down to 155-pounds.

The most logical fight when it comes to selling PPVs is the Nate Diaz trilogy fight, which could include the Lightweight title on the line if a) McGregor beats Khabib and b) Diaz agrees to fight at lightweight. Their previous two fights were at 170-pounds.

“I will always give that man his rematch,” McGregor said. “He gave me a rematch, I give him a rematch, that’s the way it is. When it will happen, I don’t know. … We will complete that trilogy, no doubt about it.”
