Dave Jones has warned his managerial successor Malky Mackay that Cardiff City fans will expect the Welsh club to be Premier League promotion candidates.
Jones was sacked as Bluebirds boss after three consecutive Championship play-off disappointments.
"The expectation levels from fans will be if you get rid of a manager, you bring in a manager that has got to do better," said Jones.
"Fans will expect them to be up there as they have been there for six years."
Top-scorer Jay Bothroyd and fellow striker Michael Chopra - who scored 31 goals between them last season - have departed while 11-goal Craig Bellamy has returned to Manchester City after his loan spell.
"They have brought in Earnie and Kenny.
"I brought Kenny down here from Rangers when he was 20 to Wolves, but he has been out of the English game a long time.
"I brought Lee Naylor down and you could see that Lee had been away from the English game for a long time.
"Playing for Rangers and Celtic, a lot of the games are very easy so you get into that easy mode and all of a sudden you come down to the English game where you have to earn your living again....and it took a bit of time."
Mackay begins his Cardiff reign at Upton Park on Sunday where the Bluebirds face a strong West Ham United side who are among the favourites for immediate promotion back to the Premier League.
But in his first interview since leaving Cardiff, Jones told BBC Sport: "They [Cardiff] need to get off to a good start.
"There is a little bit of talk of consolidation, but they have done that for the last six years. The pressure is there, regardless of what anybody says.
"If you change a manager in a football club, and I don't care what football club it is, you'll be looking to do better things as you don't change a manager to do less.
"Regardless of what they say and whether they are going to give him time, it is a club where success is expected and you've got to deliver.
"And unfortunately the one prize they wanted, I just missed out on."
