American TV host Adam Richman has stunned Celtic supporters with his "incredible" knowledge of the club.

The presenter, of Man vs Food fame, visited Celtic Park on Tuesday morning ahead of the Champions League tie against RB Leipzig as part of a filming trip for an upcoming show.

Richman - who is a Tottenham Hotspur fan and Grimsby Town investor - was gifted a Celtic shirt and took part in an interview with Celtic TV during his time in Glasgow.

While some supporters expected Richman to be little more than masquerading as a follower of Celtic, the TV host quickly changed perceptions with his knowledge of the club.

Reeling of information of the formation of the club, doing an impression of Scott Brown's iconic celebration and reminiscing over Georgios Samaras including Jay Beatty in celebrations; Richman left Gerry McCulloch staggered by his expertise in all things Celtic.

"You can't just say this is a Scottish club," said the presenter. "This is the first first British club to ever lift the European Cup and one of only five to have over a hundred trophies.

"It's a kind of legacy that people will talk about with Barcelona and they'll talk about Real and they'll talk about these other clubs and they'll forget that this club at its core has a charitable bend.

"It all came from the Marist priest (Brother Walfrid) that created this. This this legacy.

"It came from an aspect of inclusion and bringing people together, and as a kid from Brooklyn who doesn't share any Scottish lineage to go and to come to Paradise and feel this electricity, there's nothing really quite like it.

"I'm very excited and I love the tunnel when you come out, how the bricks that everyone gets to donate are there so the players get the reminder that they don't just play for themselves, they play for every one of these just under 61,000 seats.

"I'm excited. I just wish I were in better shape so I could come out there."

On how he came to follow Celtic, Richman added: "I was blessed to play in Soccer Aid 2014 with die-hard Hoops supporters like Martin Compston, Kevin Bridges, James McAvoy.

"Yes, two dear friends played for Rangers and they were shocked but I just loved it. 

"I remember seeing the picture of Scott Brown at Ibrox. I just loved that swag, just stunting on a guy like that, but I also have to say, there's one other thing too that really touched me.

"I don't like to get all emotional, this is like fun food and football. But what Samaras did for that little boy who they gave the goal of the week to (after being given the chance to score at a half-time interval). To see him carrying him around, to see someone at the apex of athletic ability like Georgios Samaras at a moment where the club had triumph and he chose to include this child, who of his own abilities couldn't be on that pitch like that spoke volumes to me.

"And yeah, I think that the style of play has been electric. I used to love watching the Hoops play."

Fans were quick to hail Richman for his knowledge of the club in response to the video.

One wrote: "I initially thought oh here we go, another celeb fan, but he surprised me. At the end of it I believe he's genuine."

Another added: "What a genuine class man welcome to paradise adam hh."

And a third commented: "What a top guy, humble, engaging and has clearly done his due diligence on our club."
