Gary Neville once trolled Liverpool fans who were on the Anfield tour and even mentioned Jamie Carragher

Gary Neville couldn't resist taking a dig at fellow pundit Jamie Carragher as he made a surprise guest appearance on the Anfield tour.

The 49-year-old, who is one of the most capped players in United's history with 602 appearances to his name, is on punditry duty for this weekend's much-anticipated fixture.

After heavy overnight snowfall, the game was under threat of postponement but after two safety meetings were held to assess the weather and travel conditions, the match was deemed safe for fans to attend.

Ahead of the game, old footage emerged that shows a group of Liverpool fans attending the Anfield tour and to their surprise, former United defender Gary Neville played the role of tour guide for a brief moment.

"Well, I've just got here to the Kop End and here's my friend who is conducting the tour," began Neville. "This is the Kop End, where Jamie Carragher famously scored two own goals against Manchester United."

He added: "And actually, it is probably the most famous thing that has happened here in the last 20 years... that didn't go down well!"

Neville then asked if everybody on the tour was happy with their current owners, to which one supporter replied: "More happy than your lot are!"

This isn't the first time Neville went viral on Sunday. Ahead of kick-off, the Anfield pitch was covered in snow and ground staff were required to shovel it away so that the playing surface was playable.

Carragher helped out by doing his bit but Neville had other ideas. In fact, fearing that United were on the receiving end of a mauling from their rivals, he proceeded to throw snow back on the pitch in hilarious footage shared by Sky Sports.

Speaking ahead of Sunday's match, Neville was far from hopeful.

“Do we have to go to Anfield on Sunday?” he joked. “Do you remember in the old days when Sunday League teams wouldn’t turn up because they said the traffic was bad or a few players were unwell?

“Obviously, joking aside, I’ve no idea how they approach this game on Sunday. Manchester United have found this fixture very tough in recent years.

“The 7-0, I was there watching it to the bitter end like many Manchester United fans were. You’re fearing not necessarily of that, but you’re wondering what Ruben Amorim can do? He can point to the Manchester City performance, but I genuinely don’t know.”
