ULSTER assumed control of Pool Four of the Heineken Cup with a 19-8 victory over the Glasgow Warriors at a packed Scotstoun as their main rivals Northampton slipped to defeat away to Castres.
Ulster flanker Chris Henry made some sustained second-half pressure count as last season's Heineken Cup runners-up secured their second win of this season's tournament and condemned Glasgow to another loss.
Henry touched down as Ulster drove over after dominating the early stages of the second half in front of a sell-out crowd at Scotstoun.
Peter Horne gave Glasgow the lead in a tight opening half, but Paddy Jackson proved the more competent kicker throughout the contest and Glasgow replacement Niko Matawalu's late try proved only a consolation.
Ulster head coach Mark Anscombe praised his side's attitude after they took control when the rain subsided.
He said: "It's not easy to come here and get a victory as other teams I'm sure will find out.
"We showed a lot of character out there, the boys battled their way through tough conditions against a very good team.
"You have got to be able to work through things because the game of rugby doesn't always go the way you want it.
"If you don't have that character and attitude to hang in there and battle through the tough times, you won't come out the right end. We have done that a few times this year, and shown there is a bit of character there.
"That's a good benchmark to build a good team from."
Glasgow boss Gregor Townsend believes his side can upset the odds and win their remaining four Heineken Cup group games and make an impact in the competition.
"We have got four games to play and we'll have to win all four to qualify. I believe we have got a group of players who are capable of doing that," he said.
