Former Hull City player Peter Swan says the pressure is building on club owner Acun Ilicali after a poor start to the season.
The Tigers are 19th in the Championship and travel to fellow strugglers Luton Town on Saturday looking to end a run of seven games without a win (D3 L4).
Tim Walter was appointed head coach after Liam Rosenior was sacked at the end of last season having finished seventh, missing out on the play-offs by just three points.
"I think the pressure is on the owner," Swan told BBC Radio Humberside.
