Aiden McGeady has opened up on the first time he witnessed a furious dressing room clash between two Celtic heroes.

The Ayr United winger and technical manager opened up on Open Goal on watching Henrik Larsson and Martin O'Neill clash in a fiery argument during a match.

However, McGeady wasn't a player at that point and only caught the argument while he was in the showers having been working at Dundee United as a kid.

The former Republic of Ireland international recalls Larsson booting in the door before an angry exchange with O'Neill during a match.

He said: "I saw one with Henrik and Martin O'Neill - I was working at Dundee United at the game as a kid and I was in the shower.

"Me and Midge [Michael Gardyne] were in the shower and half time came and Henrik Larsson has kicked the door in and him and Martin O'Neill have started going for each other.

"Martin O'Neill is like that, 'Henrik, just f***ing hold the ball in properly'. And I'm like, 'That's Henrik Larsson there'. 

"Me and Midge and Clarky is like that [shushing gesture]. John Clark is like that [shush gesture], so we are sitting in the shower.

"And Martin O'Neill was just going off on one on Henrik Larsson, and Henrik is just like, 'Oh f***ing shut up, shut up you'. And I was like, 'He's talking back to Martin O'Neill, this is incredible'.

"It was amazing, it was the first time I'd ever seen anything like that. I'd never seen anything like that. 

"You're not exposed to that as 16-year-old, proper men arguing in a dressing room."
