Jamie Carragher has lifted the lid on some of the most difficult aspect of being a pundit in a revealing video with Sky Sports. The Liverpool legend moved into punditry after retiring from football in 2013, having made 737 appearances for the Reds across a decorated career.

Carragher has gone on to establish himself as one of football most popular pundits, starring alongside rival-turned-friend Gary Neville on Sky, commentating and hosting Monday Night Football, in which he offers analysis of the Premier League.

And answering 11 questions about punditry, Carragher revealed what he found the "worst thing" to happen when live on air, as well as what he never tells Neville before the cameras start rolling.

Asked if he knows what other pundits are going to say before they begin their analysis, Carragher explained how they avoid making the same point.

He said: "A lot of the time you would know what a pundit is about to say at half-time because it might be building through the first half, or you might talk about it, certainly in Monday Night Football I know what Gary's piece is, what he's working on. We do a rehearsal.

"But the key is, when you do a rehearsal for MNF, don't give Gary Neville what you're going to say about his analysis because he might react to that and change it.

"So I think I have something I can get him on, and I'll just let that breathe and wait for when the cameras are really rolling."

He added: "The worst thing as a pundit is when you're quite passionate about something in the first half of a game and then you go to half-time and the host goes to the other guy next to you and he says exactly what you were going to say. And he's stolen what you've seen so you're left with nowhere to go.

"So I've learned that if you have strong points when the game is going on to keep my mouth shut."

One main concern for many pundits is meeting with a player or manager they have previously criticised, but Carragher is careful not to back down should that happen.

Indeed, Carragher says he respects those who have confronted him over his critique of their performance.

He added: "It is awkward at times when you bump into a player or manager you've been critical of. I've seen plenty of pundits get a bit sheepish as they see someone coming for an interview. But I've been there myself and sometimes players have pulled me on things that I've said.

"I always think, when I was a player, if I pulled someone I'd not want them to backtrack. So if I'm ever pulled on something I didn't backtrack too much. But a couple of people have pulled me and I actually respect it. People should do it more."
