St Mirren defender Marc McAusland is wary of some familiar faces in the Brechin team who will bid to knock the Buddies out of the William Hill Scottish Cup.
Three of McAusland's former Saints team-mates are in the City squad and all played in last weekend's 4-1 win over Forfar, which extended the Irn-Bru Second Division Club's unbeaten run to seven games since former Dundee United midfielder Ray McKinnon took over from Jim Weir as manager.
They include 35-year-old former Newcastle and Tottenham midfielder Garry Brady, who made more than 100 appearances for St Mirren.
McAusland said: ``Garry Brady, Craig Molloy and David McKenna are all still playing for Brechin and were at the club when I was here.
``They will definitely want to do a job over us and will feel confident coming back here. They will be familiar with a few faces and will want to get one over us.
``They are a good team with good players. They have been on a good run of form and have not been beaten under their new manager. It will be a hard test for us.''
Saints go into the fourth-round clash in good spirits after turning around their six-game losing streak with a victory over Dundee and a goalless draw at Ross County that they felt they should have won.
McAusland admits it was difficult to stick to the passing philosophy of manager Danny Lennon and assistant Tommy Craig during their losing spell but he believes it was a good learning process.
``The way Tommy and the gaffer want us to play, it's difficult when the fans are on your back and you're thinking about the results and you don't want to lose again,'' the 24-year-old said.
``But hopefully we have come through the other side stronger for it and hopefully progress on Saturday. We have St Johnstone the following Saturday, it's two home games and hopefully we can get two wins and forget about the recent defeats.''
St Mirren striker Steven Thompson is a doubt after going off with a hip knock during Tuesday's goalless draw at Ross County, while skipper Jim Goodwin is suspended after being booked twice in the competition last season.
Brechin have doubts over attacking midfielder Alan Trouten, who is struggling with a groin problem.
But with no other concerns, City boss Ray McKinnon insists his side head into the tie brimming with confidence.
He said: ``I cannot ask for us to be going to Paisley in better spirits as the boys have been terrific during my time in charge, but that does not change the size of the task in hand.
``It will always be difficult against an SPL side. We had St Mirren watched and that confirmed they are overwhelming favourites and it would be a wonderful effort from us to get anything from this tie. But we are in decent form and will give it a real go.''
