Skipper Jim Goodwin is confident his Buddies can upset the odds to send high-flying Aberdeen spinning out of the Scottish Communities League Cup.
The Pittodrie players have fashioned a sensational 12-game unbeaten run in all competitions and are hot favourites to win this evenings fourth round clash.
But midfielder Goodwin, 30, is convinced Danny Lennons side can make it unlucky 13 when the two teams go head-to-head in the Granite City.
Goodwin said: Its going to be difficult and were going to be underdogs, no doubt about it.
But I think were unbeaten in our last six or seven against Aberdeen anyway, so we have nothing to fear going into the game.
Were all very positive and as upbeat as we can be and looking forward to it.
Its a bit of a break from the SPL. We can take our eye off the league for a night but its a huge game and Im sure itll be a great atmosphere.
Saints were unceremoniously dumped out of the competition at the same stage last season when Ayr United pulled off a shock 1-0 result in Paisley.
And Goodwin plans to ease the pain of that previous defeat by pulling off their own surprise win.
He said: We have spoken about that Ayr United game and its still a bit raw, albeit it was 12 months ago. It was a real missed opportunity.
And then it was Kilmarnock who went on to win the League Cup last season and you think what if?
It wasnt to be and we didnt turn up that night against Ayr.
Ayr United were massive underdogs coming to our place last year and they got the job done.
Well be going to Pittodrie as underdogs because Aberdeen have this fantastic unbeaten record. They are huge favourites and the onus is on them.
There will be 10,000 to 12,000 there tomorrow night and its a difficult place to go but its a game we relish and really look forward to.
Aberdeen fans will turn out and well bring a couple of buses ourselves and, hopefully, we can make it a well worthwhile trip for the fans.
Goodwin admitted Saints would love nothing better than to reward their loyal fans with a place in this seasons final.
The Buddies are going though a lean spell in the SPL but Goodwin hopes that will all change with a run in the League Cup.
He explained: If we could get to the semi-final, then a final at Hampden, it would be a wonderful occasion.
It would be something to reward the fans with too theyve been great and stuck with us.
