Callum McGregor says he'll never reveal what he says in his pre-match Celtic team-talks - because "what happens in the huddle stays in the huddle."
And the Parkhead captain has also revealed the club's media team are behind his signature goal celebration.
McGregor replaced Scott Brown as club skipper and the transition has been seamless with Ange Postecoglou's team on the brink of the Premiership title.
One of the responsibilities of that is delivering the motivational talk in the famous huddle before games.
In a Q&A on the Celtic twitter, he was asked by one fan what he tells his teammates as he tried to gee them up.
But he insists he's bound to a code of omerta as he said: "What’s said in the Huddle, stays in the Huddle…"
McGregor doesn't score often but when he does, he usually whips out his signature celebration.
Asked where the 'infamous' celebration came from, he explains it was a spur of the moment decision in a pre-season game - and the club's media team couldn't get enough of it.
He said: "I think I did it on a pre-season - and the media department kept playing it so it just sort of stuck!"
He also said his favourite goal for the club was his sweet left-footed strike against Rangers at Hampden in 2018.
Although his screamer against Zenit in 2018 comes in as a close runner-up - even if the Hoops ultimately crashed out of the Europa League.
He said: "Probably the goal against Rangers at Hampden where I passed it in with my left foot. That half-volley against Zenit would be a close second!"
