Lewis Bean's try got Warriors off to a good start

Warriors started impressively with an early try but the game followed the familiar pattern of recent games with Glasgow unable to kick-on to a more convincing win and a valuable bonus point.

Sione Tuipulotu went over for Warriors before half-time, but two Carlo Canna penalties kept Zebre within striking distance.

A penalty from Duncan Weir was the only score of what was a grim second period.

​For the second week in a row the Warriors defence didn't concede a try, something that Defence Coach Kenny Murray sees as a strong jumping-off point ahead of the club's upcoming home game against Leinster.

"It's good to see our defence has held strong - that's two weeks in a row we haven't conceded a try which is a real bonus going into Leinster game," Murray told glasgowwarriors.org post-match.

"Zebre are a physical side, but, I thought we defended pretty well for most of the game. There were a couple of line breaks from our kick chase which put us under pressure, but overall we stood up to them really well.

"We knew they had real threats across the park, our whole theme this week was around caging Canna and not giving him space which I thought we did well for most of the game."

Warriors started brightly with Lewis Bean going over from close range on the fourth minute to open Glasgow's account.

"We scored a couple of good tries, but the frustration there is that we didn't take all of our opportunities," said Murray.

"Probably our balance in the game could be better - when to run and when to kick - we made a few decisions around that area that could have been better at times.

"In the second half, our discipline let us down a little bit. We conceded around eight or nine penalties in the second half. We have to be a lot better there - particularly against Leinster who will put you under pressure.

"Coming away from home, and with a few last-minute changes to the team, to come and got the win is the most important thing."

Warriors are back at Scotstoun next Friday night when they'll welcome current league champions Leinster.

"It's going to be our toughest game of the season," said Murray.

"They are playing well and are scoring a lot of points. This week they brought back in their British and Irish Lions so they have a really strong squad to pick from.

"At the end of last year we got the better of them at Scotstoun so I'd imagine they are coming here looking for a big win.

"We know what's coming and we'll have to be at our best to beat the best."
