Belief is growing but defence is still a work in progress for the surging Super Rugby finals-bound NSW Waratahs.
The Tahs enter Saturday's final round home game with the Brumbies having already secured the Australian conference and seeking a historic home and away clean sweep of that section.
They are coming off three-straight wins but anticipate a stern test from a Brumbies side, who still have a slim chance of making the playoffs and have improved markedly in recent weeks.
"The Brumbies have been playing some real quality footy over the last two or three weeks, so it's a great challenge for us to see where we are and how we're tracking," Waratahs captain Bernard Foley said.
While they ran in 12 tries last week, NSW have focused on improving their defence after conceding three.
"Defence is definitely a work on for us," Foley said.
He said there were similarities with the current team and the 2014 title-winning unit.
"When it comes to footy and finals footy it is the team with momentum who can stand up in the middle of those big games when things are under pressure and deliver," Foley said.
"That's what I think with this team over the last couple of rounds, that belief is building and growing and I'm excited by what's ahead."
Foley felt the Tahs star-studded backline was hitting its straps, but also praised their pack for giving them the platform to attack.
The 10-placed Brumbies will find out before kick-off if their finals chances remain alive.
They need the eighth-placed Rebels to go pointless from their away game against the Highlanders earlier on Saturday and also need the ninth-placed Sharks to lose early Sunday (AEST)..
The Canberra-based side would also need to score a bonus-point win over the Tahs and overcome a -23 for and against differential with the Rebels.
"We haven't talked about finals at all, it's just about preparing for the last regular season game and whatever happens after that, happens," Brumbies co-captain and playmaker Christian Lealiifano said.
The Brumbies have named 208cm twins Rory and Richie Arnold in their second row and are hopeful Wallabies' prop Scott Sio , who was named in the side, will be confirmed to play after missing last week with a shoulder injury.
The Waratahs won 24-17 in Canberra earlier in the season.
"It would be really enjoyable if we could steal one on their home ground, they obviously got one down here which is etched in our minds quite well," Lealiifano said.
