Queensland flanker Liam Gill admits the Reds' desperately poor Super Rugby campaign could cost him and teammates Rugby World Cup spots.
The Reds have travelled to South Africa to take on the Bulls at Loftus Versfeld this Sunday with just one win in 2015.
Last weekend's loss to the Rebels in Melbourne means only Auckland's winless Blues are keeping the Reds off the bottom of the Super Rugby ladder.
One of the team's best-performed players, flanker Gill is among a number of Reds with realistic World Cup ambitions but he accepts that, unless results improve, it'll be hard to make a case with Wallabies coach Michael Cheika.
"To be a Wallaby you have to be a part of a successful set-up," said Gill, who has 15 Wallabies caps.
