To mark Roy Keane's 50th birthday, Gary Neville took a walk through the woods with his former teammate, and asked him 50 questions.
We've chosen some of the highlights.
Favourite holiday destination?
I like a bit of America, the anonymity over there.
Still on your bucket list to do?
Parachute jump or a bungee jump.
Other favourite sports?
I like rugby league, I like boxing, I like watching the All Blacks.
Anthony Joshua or Tyson Fury?
Ah, I don't like any of them. That heavyweight stuff is irritating me, too much talk. None of them. They both irritate me, I'm not picking any of them.
Best goalkeeper you played with?
I suppose I'd have to say Peter, but I still think he was overrated. He was. I just don't think he was as good as everyone made out. But, he was very good.
When I was young against Forest, I played against Gazza, and he was brilliant. Overall, Zidane.

You best performance?
Ah, Gary, I don't know. I probably did alright with Ireland in one or two big games against Holland and Portugal, maybe in the World Cup against Italy.
Your worst performance?
I remember we played Real Madrid one time at home. I'd just tried yoga a couple of days before that, and I couldn't get going. It was Real Madrid at home, and I never got a kick. I was taken off, and I remember thinking, 'I'm finished at Real top level football'.
Favourite game you've played in?
Beating Spurs to win the league was good. I enjoyed that game.
Probably going to Ipswich.
I'd have to go with Dennis Irwin because I roomed with Dennis with Ireland and United. He's a Corkman. He lives five minutes away and he never gets in touch with me.
Vieira or Keane?
I thought I was better than Patrick, yeah. Is that what you're saying, who was better? Yeah, me. What are you pausing for?
If you could change one thing about your appearance, what would it be?
There's not much wrong, is there? Ah, no, I'd be a bit taller. I could have won more headers.
