Yet two of them, have walked away. Is there a pattern emerging, or are we to believe Gus would have stayed if he wasn't "sacked" and what about Oscar then walk away 12 months later..... If Sami ends up walking away at the end of the season without an explaination, will you think there is nothing up as far as the managers position at the club goes? How many more need to walk away before you think there might be an issue there?
To be honest, I can't say either way. Rumour has it Gus was hacked off he couldn't leave for the Reading job, and that he couldn't leave for the Sunderland job, or that he didn't get on with some people in the club hierarchy, or that he was unhappy with his budget etc etc. My point is, still nobody know the true reason why Gus left. It's speculation. Oscar left seemingly for very different reasons. Also speculation.
What I know for a fact is that despite of the way it ended both Oscar and Gus were successful appointments, so why would Bloom not take the same approach again?
In terms of something being "up" at the club? No, I don't think there is. Managers quit, in the words of Gus "Tha's fooball"
