What they said...

Glasgow Warriors coach Gregor Townsend

"It's a huge game for the club, even more so after our defeat to the Scarlets last week. We expect a reaction from our players tomorrow night. There have been a lot of memorable moments at Scotstoun this season and this has the potential to be another great game. We're really respectful of our opponents, they take a combative approach to every game, they challenge at the breakdown, have an excellent set piece and are ranked as the best defensive team in the competition."

Ospreys coach Steve Tandy

"There are two tough games left, away to Glasgow and Leinster, and yes that's a tough run-in, but that's what we're about as Ospreys. If we are going to successfully defend our title then we've got to front up like proper champions, starting this Friday night in Scotland. We don't want to stumble over the line relying on others to slip up, if we are going into the play-offs we want to do it on merit while building some real momentum for the knock-out games."
