The diminutive striker has had to wait patiently for his chance since arriving at Cappielow in the summer but duly took it at Dens Park, setting up Andy Jackson for the only goal of the game.
But now Campbell, 20, wants to build on that milestone and hopes his efforts on Tayside will be enough to see him gain another start at Cappielow next week.
Campbell told the Tele: "You could say we were on a disappointing run in the league but it was good to get back to winning ways.
"And for myself, I was delighted to get my first start and hopefully I did enough to earn another against Ayr next week.
"Obviously with setting up the goal, I thought I did okay and the manager was pleased with how I did. Hopefully I've done enough to keep my place in the team.
"I prepare for the game the same way every week but I was delighted to nod the start and obviously then wanted to do well.
"But for the team to get the win that was the main thing. Hopefully we can now begin picking up some more wins and climbing back up the table.
"We had a great start to the season but slid down the table a bit, but now hopefully we can get moving back up the way."
It was the second time Ton have defeated Dundee on their own turf this season - and Campbell lavished praise on his team-mates for the endeavours.
He said: "We went up there early in the season and beat them 1-0 as well and that was a hard game.
"This time it was a hard game again and we were under a lot of pressure, but we showed great work-rate, great team spirit and a great attitude to get the win.
"It was a 1-0 win but we were just delighted to get the points obviously. It has been a good Christmas but the important thing was getting the win on Boxing Day and we did that."
