Brendan Rodgers has lifted the lid on his exchange with Barry Ferguson at the Glasgow Cup final on Tuesday evening.
The two bosses were pictured shaking hands in the stands as the youth teams of their respective clubs faced off.
Rangers eventually emerged victorious on penalties after a 1-1 draw in 90 minutes.
Rodgers has since revealed how the exchange went between him and Fergusson: "[It was] just a handshake," he said.

"I don't know Barry. Apart from the game, I've never obviously come across him. So, yes, we're obviously there to watch the kids play and bumped into him before the game.
"But listen, Barry's gone into that job and I'm sure he's really privileged and honoured as a Rangers man and a former great player there and supporter.
"So, he wants what's best for his club and I'm pretty sure that him and Neil and the staff that are there will feel that they can take the club forward and meet the challenges that are demanded by the club and the supporters.
"I don't know Barry that well. But I will always be civil and if someone's a manager of Rangers or a coach of Rangers, no-one will tell me that I can't speak to him or shouldn't speak to him because that's not the world
"We might have different jobs on different sides of the clubs but we will share a lot of the pressures and that always deserves respect."
Ferguson's Rangers won't give the newly crowned Scottish Premiership champions a guard of honour when they travel across the city this weekend.
The interim Ibrox boss will, however, make a private mark of respect towards Celtic and Rodgers: "One thing I will do is, I will shake Brendan's hand and say, 'Well done for being so dominant'," he told [Sky Sports].
"There's no doubt that's been the case this year. That's got to hurt. There's no doubt it's hurt me and the staff and that's got to hurt the players as well."
