John Kirwan admits the Blues' season is on the line next weekend when they take on the Chiefs after a sixth straight defeat on Saturday.
The Blues went down 23-11 to the Waratahs in a hard-fought game in Sydney, and now find themselves cut adrift at the bottom of the New Zealand conference.
Their hopes of reaching the play-offs already seem to be over, but Kirwan believes a win next time out against the Chiefs could be enough to keep their season alive.
As a result he is not planning to rest any of his All Blacks for that one, as the Blues look to end their worst start to a Super Rugby season.
"We knew going in we had to win one of these two games away to stay in the hunt. We were hoping that was going to come tonight, so that doubles the pressure on next week," he said after the loss to the Waratahs.
"The pressure is mounting, you can't deny that. But that's where we're at, and we just need to keep focusing on what we can control and that's getting ready for the Chiefs.
"We need to win one of these games away if we're going to stay in the race. I can't afford to rest them (the All Blacks) and if the season is lost to us I don't have to worry too much after that.
"We couldn't win a trick at the moment," Kirwan said. "We're under pressure and the boys are playing with heart and commitment, but we've just got to cut out some of our discipline errors and make sure we execute a little better."
