Callum Gibbins just before the break put Warriors back in the game

The Warriors had to come back from a 6-18 deficit to score a dramatic 27-24 win at Stade Marcel Deflandre.

Adam Hastings kicked 12 points and created the decisive try by wing Kyle Steyn but La Rochelle will be regretting not making more of their first-half domination, as they only led 18-13 at the interval.

After Hastings had kicked Glasgow in front with an early penalty, the home side hit back in the sixth minute with winger Vincent Rattez releasing Dany Priso with a brilliant offload after a break from near halfway for the prop to charge over under the posts.

Jules Plisson converted and added two penalties to open up a 13-3 lead for the home side, only for Hastings to reduce the deficit with his second penalty.

However, a mix-up by Glasgow after they had won a line-out near their tryline let in La Rochelle lock Zeno Kieft for a 35th minute try.

Then, in the dying seconds of the half, Glasgow skipper Callum Gibbins mauled his way over the line for a try that was converted by Hastings.

That gave the Warriors the boost they needed and although Plisson kicked his third penalty in the first minute of the second half, flying wing Nikola Matawalu intercepted a Victor Vito pass 80 metres out and raced clear for a try that Hastings improved to put Glasgow within a point.

Plisson pulled La Rochelle 24-20 clear with his fourth penalty, but on 66 minutes came the decisive moment. Spotting Steyn free on the left flank near halfway, Hastings lofted a perfect kick into his arms and the replacement wing did the rest.

Hastings converted to put the visitors ahead and Glasgow then had to withstand some intense La Rochelle in the latter stages, which included a try-saving tackle by replacement scrumhalf Ali Price on Man of the Match Rattez.

"I thought our defence in the closing stages was outstanding," said Glasgow coach Dave Rennie.

"We showed a hell of a lot of character to hang in there and our big men did a great job around our maul defence to deny them.

"This result shows we can win ugly and it puts us right back into contention in this pool although there's still a lot of rugby to be played.

"Ali Prices' tackle late on to keep out their winger (Vincent Rattez) was also a key moment in the game. When we needed to be desperate to prevent them from scoring we were so I'm really pleased with that."

Rennie was also pleased with Glasgow's intent in attack, adding: "We exerted a lot of pressure at various times today. We were 13-3 down and struggling but we showed a lot of character to get back into the game. The issue in the first-half was we didn't earn the right to go wide and we tried to go wide too quickly.

"We got that right just before half-time when we drove them over the line for the try. We had a period where we got down to the right ends of the field and asked the right sort of questions."
