Glasgow Warriors are using Christmas as a time of much needed reflection ahead of their return match against Edinburgh following Saturday’’s derby disaster, according to the youngster who scored what should have been their winning try.

Scott Cummings’ second half score put his side 17-6 ahead against opponents who had been reduced to 14 men after just five minutes of the Murrayfield encounter.

However they sat on their laurels and, in the closing moments, threw the game away so that they now need to make home comfort count this weekend if the 1872 Challenge Cup is to go to a decider.

The 21-year-old claimed it had not been a case of Glasgow getting complacent when handed the initiative by Simon Berghan’s red card for stamping on Fraser Brown. However he admitted that the loss had been their own fault.

“We’re not the sort of team that gets complacent. We’re always pushing on. We just didn’t perform, that’s the bottom line,” said Cummings.“When you score early and they get a red card sometimes that makes you think the game’s going to be a but easier but it wasn’t.

“Credit to Edinburgh, they really stuck in there and it was a close game. They really just niggled in and kept putting pressure on us. We need to look at ourselves in that area. We didn’t perform anywhere close to where we know we can so it’s all to do with us.

“We should have played like we know we can. It’s pretty simple, in lots of areas we didn’t perform. We’ve got a lot where we have to have a good look at ourselves and improve on them because there are a lot right now.”

After a tough few weeks the Warriors players have been given an extra day’s holiday while Edinburgh return to training today, but their coach Dave Rennie has told them to use that rest time properly.

“He said we had to have a good look at ourselves but we knew that,” Cummings reported. “So go away, enjoy Christmas then come back in and make sure we are really ready for it. They’re coming to Scotstoun, our home patch and we don’t want to repeat that performance. Obviously they are a team on a high as they’ve won a lot of games but we need to get back into the way of things.”
