Sean Lineen says his players showed true Glasgow spirit as they toppled three-time European champions Toulouse in their own backyard.
Glasgow stunned the 18,700 crowd at Stade Earnest Wallon by winning the Pool 6 encounter 33-26.
But, with fifteen minutes to play the visitors had amassed a 24 point lead, and had to withstand a huge fight back from the home side as the clock ticked down.
"We knew their would be a backlash, and sure enough it came," said Lineen. "It was never a done deal, not until the final whistle.
"Toulouse have great strike runners all over the park and they can and will hurt you if they have a sight of the line.
"But I'm delighted with how we defended. We showed great character.
"Our team showed true 'Glasgow spirit' and it's about time we recorded a win like that."
Glasgow will not qualify from Pool 6 after narrowly missing out to Bath in Rounds 3 and 4, and Lineen said: "We ran Bath close twice and we knew we can perform on the biggest stage against the biggest teams. Today we proved it and I'm just so proud of that performance"
