St Mirren boss Alan Stubbs was pleased with the fitness of his players as they triumphed over Kilmarnock in a penalty shoot-out.

The Buddies beat Killie 3-2 on penalties after a goalless draw in normal time at Rugby Park as the League Cup got under way.

The visitors claimed a bonus point win despite not having played a proper warm-up game in pre-season after their friendly against Bolton was cancelled.

Stubbs said: "In terms of the overall game I thought we looked quite fit, which was good,"

"It doesn't surprise me in terms of effort that the players put in, and the performance was an added bonus.

"We weren't too sure because this is our first competitive game, but coming away and managing to get the bonus point is good, but I would be more happy if we had three."

Stubbs handed debuts to six players including Cole Kpekawa who signed earlier on Friday, with Hayden Coulson impressing at left-back.

Despite the performance, Stubbs is looking to recruit further before the end of the transfer window.

He said: "I am hoping potentially we will need at least another four, maybe five.

"I would like to bring a striker in and another midfielder, a couple of wide players. We will see, hopefully we will be busy."

Steve Clarke saw Lee Erwin, Gary Dicker and Kirk Broadfoot miss from the spot in a poor shoot-out, but he was unconcerned with the loss.

"We are still a long way away from the start of the SPL (Scottish Premier League), which is our main target to be physically ready for," he said.

"We lost the penalty shoot-out and made the group a little bit more difficult.

"We need to make sure we win the next three games to get ourselves 10 points which should be enough to take us through to the next round."
