Rosler became Cellino’s fourth appointment since the Italian became owner in April 2014 and he has had pubic fall-outs with some of his previous employees.
Cellino branded the former academy manager Neil Redfearn as “weak” and “a baby” after the owner returned to office earlier this month, having served a Football League ban for a tax conviction in his homeland last year.
Cellino hired 36 coaches during 22 years as owner of Cagliari but has a vision for stability at Elland Road and has said that there is no rush to win promotion to the Premier League.
He told Sky Sports News HQ: “We don’t have to rush. We have to build a strong team – that takes time. We have to build a mentality and teach the players at Leeds to build something important.
“Looking for the big money of the Premier League doesn’t help you. That is a lot of pressure and you can make a lot of mistakes. We don’t need financially to rush. We have a balance and the costs are under control. We want a team that can take us as far as we can.”
Sky sources understand Redfearn is set to leave the club and an announcement confirming that is expected in the coming days.
The terms of the contract he agreed late last year allowed him to return to his old role at the academy after he was relieved of the head coach position he took up late last year in May.
He remains on gardening leave for now and is thought to be on the verge of an Elland Road exit instead.
