Nelson talks about McGregor at a pre-fight conference:
I haven’t trained much with Conor since his last fight, but we did a week in Iceland. We always focus quite a bit on grappling, so I think his focus will be as it has been. Maybe focus on some specific things for his opponent, who is going to be again, bigger and longer. Some tactical strategies maybe for him specifically. Also, I think he needs some time to train. Like we’ve seen, he ‘retired’ that other day because he felt like he wasn’t getting the space to train. There was too many media obligations and things like that. If that’s how he feels, he definitely needs to get time to train on his own, and get some space.
