GLASGOW WARRIORS stalwart Duncan Weir has promised to repay the thousands of fans who make Scotstoun such a great place to play by beating Ulster on Saturday and doing their best to earn their second home semi-final in the Guinness PRO12 in the knockout stage the following week.

Like all his team-mates, he is driven on by memories of the occasion last year when they beat Munster to earn their place in their first major final and Weir says he is desperate to relive that magical experience.

"Days like that Saturday are only going to come if you get that home victory in the league to earn that home semi," he said.

"The atmosphere with the guys all jumping about like headless chickens after the game was brilliant, the fans staying back and everybody partying on after the full-time whistle. It was great, I just know everyone will be wanting that home semi final feeling again."

This year, they could get it two weeks on the trot. This week's match against Ulster is almost as big a game, even though Glasgow are already guaranteed a place in the league play-offs.

"To have a chance of staying at home for the next round, they certainly have to beat Ulster and depending on results in the other games being played at the same time, they may need to score four tries and claim a bonus point.

"Ulster have been at the top end of the league for a number of years now, the way they attack, their set-piece is outstanding and they have a number of plays of the tail of the line out that draw in the defending guys so that they can cut open a lot of teams, they score a lot of tries that way," Weir pointed out.

"If we can match them physically the set-piece battle is going to be the key - and make sure our attack breaks down their defence, because they make it a huge contest at the tackle, then we have every chance. I know the boys are up for it."

The days when playing at home were hardly any advantage to Glasgow have long-since disappeared and Weir is banking on that intimidating atmosphere created by the sell-out crowd this week to roar his team to triumph and repeat the job in the knockout stage.

After all they have not lost at Scotstoun in the league for 18 months - since November 2013 - and he has every right to feel proud of the venue.

"It looks like a rugby venue now, not like a rugby pitch in the middle of a running track any more," Weir said. "It looks like a purpose build rugby venue and has got that great vibe about it.

"We have had a number of great victories here and our league form at home has been terrific. That home record is a huge privilege to the guys and it certainly feels as though this really is our home.

"The enthusiasm is great, 10,000 sold out weeks in advance, it is a big achievement for the club and credit to the rugby public who are coming out and supporting the guys. I remember playing at Firhill when there was barely 3,000 there and not much of an atmosphere, now we have got a group of fans supporting us wherever we go. It is great to have that backing behind us."
