Pressure is mounting on Cardiff City manager Omer Riza with the Championship club increasingly concerned over their league position.
The Bluebirds are one point above the relegation places in 21st following Tuesday's 2-1 defeat by fellow strugglers Luton Town, with the team booed off the pitch after the final whistle.
Luton's triumph mean Cardiff have suffered three successive league losses, while they have managed only four wins from the past 24 matches.
BBC Sport Wales understands Cardiff's hierarchy are aware of supporter unease at the club's current situation, with nine games left this season for Riza's team to turn their form around.
Riza has been in charge of Cardiff since replacing Erol Bulut on a temporary basis in September before being given a deal until the end of the season in December.
The 45-year-old enjoyed an excellent start to his tenure, winning four of his first seven games.
But the former Watford coach has only picked up four more victories in his next 24 matches.
Riza brushed off the boos on Tuesday, saying it was his job to take such criticism, but also warned his players he would be making changes in their fight to avoid dropping into League One.
