Stephen McGinn has told Saints fans that the team will make up for Saturday's disappointment against Dunfermline.
The captain confessed to stmirren.com that Saturday's 3-0 defeat to the Pars wasn't good enough.
Despite being Saints' first loss in six, McGinn was frustrated by the manner of defeat and apologised to the 1000+ St Mirren fans who travelled to East End Park.
But while he was disappointed to lose, he cautioned that there is still a long way to go in the season and the team will work to improve.
I apologise to the fans who came in great numbers and ask for them to turn out again. We'll repay them for that over the long run.
"It's so early on, but in any game to get beat the way we did is sore and we have to take our medicine.
"They are a good side and it's a tough place to come. We can't defend as poorly as we did. If we keep defending the way we are we are going to have afternoons like Morton and here and it's not acceptable moving forward.
"There's a long way to go and we still play each team at least three times. On paper it is still a reasonable start with winnable fixtures to complete the first round of fixtures.
"We take our medicine, we'll work on the negatives and we have to improve defensively. We need to be better and far more resilient."
The Buddies have won their last six home matches in a row and are back to playing hosts this weekend as Queen of the South come to Paisley.
McGinn says the team will be aiming to keep up the good home form on Sunday in a bid to look to get back to winning ways.
Our home form is really good and it was a different game going to Dunfermline.
"We like playing at home and fancy our chances of beating most teams there.
"The last run of home games was very profitable for us and we have to look to do the same again."
