Reds interim captain James Slipper says he was disappointed with the way they played in their Super Rugby opening loss to the Brumbies in Canberra.
Slipper was standing in as captain for the Reds in the absence of regular captain James Horwill and vice captain Will Genia who were both out injured.
"It was really disappointing how we played tonight," Reds captain James Slipper conceded after the 24-6 loss.
"The ill-discipline really hurt us and we let the Brumbies get good field position, and we just couldn't hang on.
"I don't think we gained any momentum through the forwards and we couldn't deliver any good ball to the backs."
Wallabies fly half Quade Cooper who made a quiet re-entry to Super Rugby without his regular partner Genia praised the Brumbies defence but also blamed their ill-discipline.
"It was great defence from the Brumbies and there weren't many chances for us," said Cooper.
"There were a few, but ill-discipline let us down a little bit."
Brumbies captain Ben Mowen said that it was nice to get one over the Reds for a change.
"They beat us twice last year and you try not to carry things over between seasons, but that really hurt us and we weren't happy," Mowen said.
"We left a lot of opportunities out there but I'm really happy with that."
Mowen said the Brumbies forward pack, which has been bolstered by the recruitment of Wallaby flanker David Pocock, had laid the foundation for the win.
"The breakdown is obviously a huge strength for the Reds and I think we matched them there tonight," he said.
