If Glasgow Warriors coach Dave Rennie had targeted a bonus-point win in advance of the European tie against Lyon yesterday, then there would have been a speedy reappraisal of the situation from Rennie pre-game and, probably, after the first whistle sounded.

Yesterday was not the weather for free-flowing rugby. Indeed, the only flow to be seen was the amount of sleety rain heading for the drains around the venue. It was cold and dreich, meaning, as Rennie eluded to, Plan A was binned and a revaluation drawn up.

“In the end, what we talked about was making sure we won,” Rennie conceded. “The fact that we started so well, and got a couple of tries in the first 20, obviously gave us a glimmer of hope. That last part of the first half.

"I think we just needed to keep playing territory and putting pressure on them and trying to force some errors.

“But we made a couple of errors ourselves down our end, and then we played without the ball for the last quarter of an hour of the first-half.

“It was tough conditions and both sides made a lot of errors. What we were trying to do was get it to the right end of the field and try to register some points from that.

"We probably should have scored when we were going around the edge, but maybe going wide from that in these conditions wasn’t the best option.”

Pleased with the win, Glasgow’s difficulties in the set-piece did cause some consternation amongst the Glasgow coaching staff.

“The scrum was really disappointing, and we’d expected to dominate,” Rennie admitted. “The boys were saying they were having trouble getting grip on the ground and we had examples of where guys were just sliding across on their studs.

"We are not looking for excuses, both sides had to scrum on it.

“From a line-out point of view, I think we had a few opportunities to put ourselves in a position for a bonus point. But we didn’t do a good enough job but, like I say, we need to be sharper next week.”

However, there still appeared a warmish contentment from Rennie at the end of a week where Glasgow has taken nine points over 160 minutes against the Top14 outfit, meaning a prolonged run in Europe is still very much alive.

“I guess we’re sitting in the coaches' box, in the dry, and you’re scratching your head at some of the errors. But it was difficult. We’re happy; we’ve got ourselves in a good spot, in Europe, destiny is in our own hands, and I look forward to Cardiff.

“Obviously, if we can knock Cardiff over, takes us to 18, with a bonus 19. We’d be pretty close I’d imagine,” said the Kiwi, looking in to the New Year.

Viewing the immediate horizon, Rennie prepares his team this week for the first 1872 Cup game of the season, against Edinburgh, with the injury yesterday to hooker George Turner – ankle damage accompanied with a bit of concussion – his main concern.

“He just got caught in an awkward position,” said Rennie, who himself maybe similarly disadvantaged given first pick No.2 Fraser Brown is out medium-term with a knee injury.

“They normally come in groups, don’t they? We lost Fraser last week and George today, but hopefully it’s not too bad,” says the Glasgow coach who does have cover in that position.

“Obviously Grant Stewart played today and Kevin Bryce has played a bit of hooker, a bit of prop, and is now back to hooker, and he’s been with us the whole time and we are reasonably comfortable with that.

“Probably, we’ll put out our strongest possible side next week (versus Edinburgh) and we’ll know what that looks like by Monday.”
