Glasgow coach Gregor Townsend has reiterated that his side will need to be at their best to overcome Zebre on Friday.
The Warriors travel to Italy to face a resurgent Zebre side fresh from their first ever competitive victory against the Cardiff Blues last week.
Townsend's team currently sit atop the RaboDirect Pro12, having emerged with three victories from their opening three fixtures, and have yet to conceded a try. However, the coach has warned his players that they will need to be on top form to keep their winning run going.
"They are playing some good rugby just now. They have had some tough challenges so far against Connacht away, Munster at home and Cardiff away last Friday," Townsend told the Glasgow Evening Times.
"They got a great win against Cardiff - their first in the RaboDirect Pro12 - and scored 30 points in the process.
"They have really developed an attacking edge to add to their strong set-piece play. Brendon Leonard, the former All Blacks scrum-half, who previously played for Super Rugby champions Chiefs, has been key.
"As has their stand-off Luciano Orquera. He played superbly in Italy's win over France in the Six Nations last season and can cause us problems."
The former Scotland international, who took over the post at Scotstoun a year ago, also paid tribute to the efforts of Chris Fusaro and Chris Cusiter against Leinster last week - both of whom had spent periods out of action thanks to injury.
"I was pleased with how both Chris Cusiter and Chris Fusaro - two players who have spent long spells on the sidelines injured - performed against Leinster," added Townsend.
"You have great empathy for anybody who is unable to be involved in the game for any length of time and it was great to see them play so well. They both got stuck in physically too. That shows they are back to their best.
"We will change things around for this game. Al Kellock is available again as is Niko Matawalu and they will both be involved.
"Guys who have played a lot of rugby recently may be rested. Guys who have been knocking hard on the door may come in."
