Despite losing their Super Rugby opener to the Crusaders at the weekend, Brumbies lock Sam Carter hailed the attitude displayed by the new players in his side.
A new-look Brumbies side were huge underdogs against the seven-time champions in Christchurch but came close to causing an upset before eventually suffering a 17-13 defeat.
And Wallaby Carter, who is the team's co-captain, was encouraged by the performances by several new players in the Canberra-based outfit's ranks.
"The most pleasing thing out of the game was the attitude from all the boys especially the blokes that haven't played for the Brumbies before," he told AAP.
Former Force flanker Chris Alcock has big boots to fill as David Pocock's replacement but did well in his Brumbies debut while Joe Powell caught the eye with an impressive display at scrum-half.
Powell was set to be the Brumbies' back-up number nine but got his chance in the run-on side after Pumas scrum-half Tomas Cubelli suffered a serious knee injury.
Another player whose stocks have risen is front-row Nic Mayhew, who stood in for injured Wallabies prop Scott Sio.
"That's something the Brumbies pride themselves on, having blokes come down with something to prove," added Carter.
"Obviously we had a lot of new faces out there tonight and they all wanted to put their hand up and prove something."
