The Leeds head coach lost his job after 12 games in charge at Elland Road on Monday morning.
Usually, outrage greets yet another Cellino sacking at Leeds. There has been plenty more this time around.
But, when a lot of fans are asked for their genuine opinion of Rosler, many aren't too surprised or displeased that the German is gone.
It's a little bit like the Darko Milanic appointment and sacking. A reserved, slightly boring character has come in and the Leeds side has started to play a more reserved and boring style of football. Under any other owner, a few more weeks would be given at the least. But not Cellino.
And the reason the word 'philosophy' explains it all is that Rosler over-used it so often Leeds fans started to grow bored of every one of his post-match press conferences.
Brendan Rodgers was the same at Liverpool. Using buzzwords doesn't work in football unless you have results to back them up. That's why Mauricio Pochettino and Louis van Gaal, who also like to discuss abstract concepts, are still safe in their jobs.
The problem is that Rosler didn't have a philosophy. He had one style of play and it was the wrong one. Whenever he announced that Leeds won't change their way or approach, he was basically admitting he didn't have a Plan B - or that he was too lazy to find one.
Yes, the German did admit the need for change after the Birmingham City defeat. But there wasn't much against a Brighton side that were poor on the day and still left Elland Road with a win.
Rosler's system was a 4-3-3. That's pretty much all you can say about it. There wasn't much else unique about it.
Chris Wood was isolated up top, the Whites defence let cheap goals in regularly and the Leeds midfield didn't create anything.
If Rosler finds work again, he would be better not to argue with reporters when questioned about his approach but rather to actually do the job of a football manager: to manage situations, adapt to them and not continually insist his way is the only way. Especially when it is clearly the wrong way.
