He starred in the final the last time Saints won this trophy, scoring the winner as the Buddies ran out 2-1 victors over Hamilton Accies back in 2005.
John Sutton was a fresh faced 21 year-old when he nodded home David Van Zanten's cross to ensure there would be black and white ribbons on the Challenge cup.
It was the catalyst for a double winning campaign as the Buddies secured promotion to the then Scottish Premier League later on in the season.
This time around it's a different story. This time Saints are going for the trophy while fighting to stay in the Ladbrokes Championship.
At 33 years old the striker is one of the more experienced heads within the squad and could well be playing in his last cup final. And, after a long career, the Englishman knows that finals don't come around all that often.
It's very exciting," he said of Saturday's match before reflecting on 2005's win.
"I remember going into that game and the manager told us that a lot of players go through their careers without winning anything. We managed to win that day, that was a great achievement and it kicked us on to bigger and better things.
"Cup finals, whatever they are, don't come around very often. I think Hibs and Rangers and even Hearts have proved that over the seasons being in the lower leagues, so it'd be a great achievement for this group of players.
"Everyone is desperate to win," he continued. "It was different circumstances back then as that kicked us on to win the league that year which was a brilliant double. It won't be the same this year but hopefully it could kick us on to league survival.
"Hopefully it's a bit of a confidence boost. But we can't look too far whether we win or lose the cup final, it's not going to determine whether we stay up or not. You want to win at everyone so to take that and give the fans a good day out that would mean a lot to all of us.
"There's a confidence in the group, there's no doubt about that. Dundee United are a good team but we know if we play as well as we can then we can cause any team problems."
Saturday's venue holds a special place in the striker's heart after having two spells with Motherwell and he is looking forward to what he believes will be a good occasion.
Fir Park is brilliant for atmosphere," he said. "It's quite a tight pitch and the fans are right on top of you. We were lucky when we played the final at Airdrie as we had pretty much three quarters of the stadium, it was a brilliant atmosphere and I'm sure that will be the same this time around.
"It'll be nice," he said of returning to the ground before joking; "Especially since they got the pitch sorted out in the last few years!
"It's a fantastic stadium, I enjoyed my time there. The good thing about it is that it's compact and there should be a really good atmosphere."
