The last time the sides faced each other in Wales, the hosts emerged 16-13 victors but following last week's 25-0 win over Border Reivers, Glasgow are looking to step up their game yet again. Sean said: "This week's game will be very physical. Ospreys have a real aggressive defence and it'll be a big challenge for us. This'll be a particularly big game for Andy Newman in the second row as it's the first time he'll be facing his former team-mates."
Glasgow travel with the same 22 but one change in the starting XV as Andy Henderson and Scott Barrow swap places, meaning Scott starts and Andy is on the bench. Sean added: "The centre is still an area that I'm looking at as we want to develop it, particularly given the exciting back three we have. Looking towards the Autumn Tests too, we need to make sure our players are fresh."
