Nah, and it wasn't my intention to make that comparison. In line with the thread title though, they both were in charge longer than was good for our football. At least for both of them the curtain came when the results began to clearly reflect the decline.
I think with both coaches you could see a somewhat similar pattern: you saw the cracks opening up quite early, bottom line everyone could see that they weren't a good fit for the squad, but since Bayern have managed to create a club culture of ambition the players pulled themselves together for the business end of the season and won domestic titles. Then came the new season, there were no knockout games or title home stretch to put things into perspective, games weren't as make or break, so the cracks resurfaced and since the coaches didn't have the "recently signed protection" anymore things quickly spiraled out of control for them.
I think if you just put it as "well results turned sour at some (random) point" then you ignore the predictable nature of these sackings. I think you see this quite often: some purple patch run in that papers over the cracks, everyone is blind to the fact that the team actually isn't highly functional and then momentum gets reset during the summer break and suddenly reality kicks in and you things collapse right from the start. An example of this would be Tayfun Korkut, who had a miraculous streak after taking over Stuttgart mid season, getting an amazing string of results playing bad football and then the following season they god relegated. Another example would be Domenico Tedesco, who won 2nd place with Schalke, playing games against relegation fodder where you couldn't tell which team was on top of the table and which was on the bottom and then the following season they completely crashed after the club had just given him a long term contract.
