You might think that the biggest worry Albion Rovers midfielder Gary Fisher would have at the moment would involve the imminent challenge of pitting his wits against Celtic’s Scott Brown.

But for Fisher, who will be putting his allegiances to the champions to the side for the day, his major concern is that his young son might belt out a Celtic song or two as he walks onto the pitch with him.

The sight of an Albion Rovers mascot belting out ‘Come On you Boys in Green’ might not be the greatest inspiration for the Cliftonhill men, not that they need any added incentive ahead of the club’s biggest day in years.

And there is no doubt whatsoever that Fisher will be doing everything in his power to end the treble dream of his boyhood heroes.

"I'm a Celtic fan, my whole family are so it's a big game for everyone,” Fisher said.

"I've been getting a bit of stick from uncles, asking me what I would do if I scored? I said, 'What do you think?' I'll be giving it everything.

"People assume that you'd be more up for it against Rangers - but as a Celtic fan there is a bit extra. You feel like you want to prove yourself even more. Come Sunday, I won't be a Celtic fan.

"I have 20 friends and family coming. It's a big occasion and my wee boy Rocco is a mascot, so he will be walking out with me.

"My only concern is that he might start singing Celtic songs! He's only four. His main thing is just running about shouting Celtic.

"When we walk out he will probably think he's on the wrong side but it's a great memory for him.

"It'll be brilliant to look back on it and it's a big day for all of us in front of a big crowd.”

Tomorrow afternoon’s match won’t present the first opportunity for Fisher to go up against his beloved Hoops, although he will be hoping for a better outcome than the last time he faced them.

"It's the Scottish Cup and it would have been a big game no matter who we got,” he said. “But the fact it's Celtic just makes it all that bit more special.

"I played against Celtic for Killie. We lost 2-0 and I came on for the last 15. It was 2-0 already so it wasn't my fault!

"We will be up against the best players in the country but there is no point doubting yourself.

"Everybody out there is doing that for us. There is no expectation on us, so it's an opportunity for us.

"It will be hard to get a result against Celtic but we will do what we can and hopefully cause an upset."

Like all of the Rovers players, Fisher combines playing for the club with a full-time job, although he hopes that far from tiring him out for the game, his chosen profession can give him an edge.

"I work as a personal trainer outside of football,” he said. “I've just qualified recently.

"When I went part-time, I wanted to do something that could run alongside the football. I have free hours during the day and this suits.

"In terms of fitness, I'd fancy myself to be as fit as anyone on the pitch. I'll match them in that way.

"The personal trainer job doesn't impact on the football. I don't really need to take days off to rest or anything.

"I am mad for being fit and it runs alongside the football, and helps me."
