The German has been unveiled as the successor to Neil Redfearn at Elland Road.
It has been coming for a long time but now it is confirmed, Neil Redfearn is no longer head coach at Leeds United.
It is yet another management change for Massimo Cellino. He has now seen Brian McDermott, Dave Hockaday, Darko Milanic and Neil Redfearn out the exit door - Rosler is under immense pressure to get things right.
But rather than focus on the negative Leeds fans will at least have a manager who employs an exciting style of play.
The German likes his team to apply pressure high up the pitch and retain the ball when they have it. He may have finished his time with Wigan poorly, but he had previously taken them to the FA Cup semi-finals with a win against Manchester City and the Championship play-offs. Prior to that, he had guided Brentford to a strong position in League One - so he has pedigree.
Leeds fans will hope he can be the one to keep Cellino out of the headlines and get Leeds back at the right end of the table.
