Tim Swinson was outstanding for Glasgow

A hard-fought affair looked set to be decided by the teams' respective kickers before the game swung decisively in favour of Rassie Erasmus' men when Warriors full-back Stuart Hogg was yellow-carded with 10 minutes left.

That opened up the space Kiwi centre Francis Saili needed to grab what was the winning touchdown that sends his team through to the last eigjt.

Warriors still had an opportunity to grab a late win but the chance of a drop-goal came and went.

Glasgow were left with a losing bonus point but their hopes of escaping the pool stage for the first time now rest with next week's do-or-die clash with Leicester at Welford Road.

Gregor Townsend said: "We will have to play better but we are looking forward to it as we always knew we would have to win next week, even if we had won today.

"I still believe a win will get us into the quarter-finals but that will become clearer in the next few days.

"I believe in this squad and I believe we can play better. We need to up our game by 20-per-cent next week.

"We knew how important this game was for us and for the club as a whole and to lose it in the last eight minutes was even more disappointing.

"The better team won, at times we played well but on a few occasions we weren't at our best. They defended better than we attacked."
