Cardiff chairman Peter Ridsdale has warned manager Dave Jones that he has two games to save his job - just one day after giving him the board's vote of confidence.
"If we don't win or take good points from the next two games then the pressure would be such that we would have to change," Ridsdale told the South Wales Echo.
"It's been made absolutely clear the team have to perform or changes will be made at the top.
"I'm not saying if it will be one, two or 10 matches when we would have to make a decision.
"But I want to see an immediate upturn in fortunes."
The Bluebirds are currently languishing in 20th position in the Championship table and chairman Ridsdale has cited the club's next to fixtures - against Ipswich on November 24 and Leicester two days later - as pivotal in determining Jones' future.
"If we don't perform against Ipswich, in our next match, and Leicester then, of course, we would think again," he added.
"I met Dave and explained the situation in blunt terms.
"Can he fix it? If he can then he had better fix it now."
