The 36-year-old music producer told retired professional footballer David Ginola - who has played for Tottenham Hotspur, Aston Villa and Everton - how he had been led to believe standing behind the goal was an official position in soccer.
Naughty Boy revealed: “When I was a kid my favourite sport was Rounders. In football they used to make me, not the goalkeeper, they used to make me stand behind the goal for the extra goalkeeper."
When everyone laughed he asked: “That is a place, isn’t it? That’s an actual role isn’t it?”
Ginola replied: “It doesn’t exist in football, but… they invent a role for him in football... behind the goal, to collect the ball.”
Naughty Boy insisted: “I was the real goalkeeper.”
Ginola joked: “Behind the goalkeeper… behind the stadium... he was in the street, just in case.”
Miller asked: “You didn’t have a high-vis on did you?”
Ginola later told the Telegraph cameras: “Naughty Boy’s knowledge about the beautiful game needs to be improved or re-assessed or something. ‘My position on the football pitch was behind the goal…’ I don’t get this. I’m still not getting this.”
Naughty Boy said in the Telegraph: “The important thing is I felt important. Any kid out there who’s been made the keeper of the goalkeeper, you will thrive and you can be anything you want.”
Even hosts Ant McPartlin and Declan Donnelly couldn't help making fun of Naughty Boy's made up football role.
McPartlin laughed: "Basically he was the kid who ran into the road and got the ball."
Meanwhile, Frankie Bridge took part in the latest Bushtucker Trial which saw her spun around in a box while being pelted with rotten vegetables, fish, cheese, raw egg and curry.
Bridge admitted: “I get motion sickness, so bad…”
The Loose Women presenter and former Saturdays singer was chosen for the challenge after the celebrities decided to pick names out of a hat.
She had to answer trivia questions as she was spun around, and managed to win 7 out of 9 stars.
