Lennie Lawrence is returning to Cardiff City as assistant coach to Paul Trollope.
Former Newport County academy coach James Rowberry is also being promoted to an assistant role having impressed as first team coach.
Trollope, who took over from Russell Slade this summer, has also made the Wales national squad’s head of performance Ryland Morgans performance director.
Head coach Trollope, currently assistant to Chris Coleman with Wales, said: “I am delighted to finalise my backroom staff ahead of the forthcoming season.
“We’ve worked very hard over the past month to secure their services and I feel it’s a highly experienced, driven and ambitious staff.”
Lawrence – who worked with Trollope at Bristol Rovers – joined the Bluebirds as a consultant in 2002.
The 68-year old then succeeded Alan Cork as Cardiff boss and led them to promotion in his first season, winning the Football League second division play-off in 2003 against QPR.
Morgans previously worked for Liverpool – with ex-manager Brendan Rodgers – and Fulham.
Martyn Margetson has also agreed a new contract to stay as goalkeeping coach.
“We are delighted to bring people with the experience Dr Ryland and Lennie have to the club and hope that they can play an important role in helping us achieve our ambition of promotion back to the Premier League,” chief executive Ken Choo said.
“We have put together a strong backroom coaching team this summer which we believe will help maximise the potential within our playing staff.”
Former first-team coach Scott Young becomes academy defence coach and club ambassador.
