as long as he didn't fluff his first pass.
The English youngster made an assured debut at right-back in the 1-1 draw against Hibs last weekend.
But he admits the butterflies were churning before the game started - even though he has played in pre-season friendlies against Liverpool and German cracks Borussia Munchengladbach.
The 19-year old said: "I just didn't want to let the occasion get to me. Once I got that sorted I was fine.
"You have to be like that as it's a game of football at the end of the day.
"The most nerve-wracking thing was the first pass and I made it and it went okay so I picked up a bit of confidence from that.
"I was relaxed as I played in pre-season and then had games like Liverpool and Munchengladbach, so I just wanted to get through the game and get the three points, but unfortunately we never got them all."
Fisher has earned rave reviews for his displays with the Development Squad and has been working with the first team at training for some time.
And he has clearly caught the eye of gaffer Neil Lennon and the rest of the first-team coaches at Lennoxtown.
Now he's hoping to kick on with Celtic while acknowledging he is still serving his football apprenticeship.
He said: "It was a proud moment. I came up here at 16 and to make my debut is what I have been working for, but now I need to push on.
"I need to keep going, training hard and hopefully get more minutes.
"I only found out I was playing in the dressing room, but I kind of knew it was coming as a couple of the boys were saying you're the new right-back, so I had a feeling.
"But I still wasn't too sure and then the gaffer said it and it was a big surprise. There are mixed emotions as we should have got the result, but obviously I was pleased to make my debut."
His time spent training at Lennoxtown with the first team helped ease some of the tension of making his debut and he praised his more senior team-mates for making it a smooth transition.
He told the Celtic View: "They know me and they just told me to go out play my normal game and guys like Broony, Virgil and Efe all helped me."
Now his sights are set on remaining in the first-team frame for Sunday's Firhill shoot-out.
And Fisher is hoping to be pitched in at a ground which is a second home for an Under-20 Celtic player.
"I know the ground well and that is what I am working towards - getting as many minutes as I can and hopefully I have staked a claim," he said.
