Glasgow head coach Sean Lineen looks like reverting to his strongest line-up for Friday night's Magners League clash with the Ospreys after admitting his decision to rest players backfired against Newport-Gwent Dragons.
The Warriors went down 30-19 in Wales to surrender their 100% start to the season.
Lineen made six changes from the previous weekend’s win over the Scarlets and believes some of the new faces let him down.
"Guys were given an opportunity, there was a bit of trust there; certain guys performed well and others didn’t. There will be words said but the guys know what they need to do."
He added: "Our set piece was also poor and if you do not get things like that right away from home then you are not going to win games.
"However, we know we can fix it and will do so."
