Marc McAusland admits his side must repay the St Mirren fans after Saturday's 4-1 embarrassing home defeat to Ross County. This was not the way the Buddies wanted to prepare for their meeting with Celtic on Sunday in the Scottish Communities League Cup semi-final at Hampden. St Mirren have yet to score against Celtic since Danny Lennon took over as manager. However, the defender believes a win on Sunday would be the best possible way to make up for last week's drubbing by the Staggies. He said: "To get beat 4-1 by anyone at home is shocking so we really need to kick on this Sunday. I've tried not to think about that game too much. I've tried to erase it from my memory. It's hard to do that though as the gaffer has been on our case a bit. You also feel guilty about the fans who have paid money to come and watch that. But we have a chance to try and repay them, more so as it's not just another league game. The fans are looking for us to do that and we owe it to them to reach the final."
