After letting slip a 19-3 lead at the break to go down 32-26 at the end of 80 minutes, Ireland scrumhalf admits dat hulle nie lekker voel nie.
Murray, who will win his 50th Test cap on Saturday, says: “I think we’re really angry at ourselves. We can right the wrongs this weekend.
“We ended up standing off the South Africans and soaking a few tackles, which gave them front-foot ball and allowed them to get into their rhythm.
“The atmosphere in camp is one of annoyance and that we left things out there.
“You can feel it around the place. People are hungry to get training and just go ahead, which is good.
“I think we could have snatched it at the weekend, so I think there’s such motivation there, genuinely.
“We definitely believe we can do it.
“We’ve just got to stay tight, stay together.
“It’s our last game of the season, and it’s a massive one and we’ve just got to give it everything.
“This a chance at history, it would have been unbelievable to have won at Ellis Park and it’s very disappointing the way it ended.
“But we’ve got a chance now to win a series in South Africa which is very, very difficult and very, very rare.”
