I think Gary is full of shit and is just protecting his mate. He'd have sacked Solskjaer 50 times if he was in charge of Salford. Remind me how many years Guardiola spent in his previous clubs? He spent 3 years at Bayern and 4 years at his beloved Barcelona. Both he left because he clashed with the owners. The only raeson he's stayed at City for so long is because they've basically laid the entire set-up for him, his friends are there and he as unlimited money to do what he wants. Managers are always gonna stay at the club they are happy at, no matter if it is Conte or Pep or whoever. The reason Conte left Juve and Inter is absolutely sensible. Imagine a club wanting to sell all your best players you fought so hard to get? You think Pep or Zidane are gonna stay in that situation? Zidane left Madrid twice because of disagreements with Perez.
We have to stop with the absurd notion that any manager that comes here first has to agree to be long-term appointment or else he's not hired. There's no such policy at any other top club. Managers are judged by their performances. If they perform, they can stay as long as they like. If they don't, they're shown the door. We're the only club stuck in the last century still waiting for the next Busby or the next SAF to lead us to the promised land. No such thing is ever going to happen by us looking at it. It might happen randomly, but never as a goal. I can assure you that SAF didn't come here with the idea of staying here close to 30 years, that's for sure. It's also funny to me when people say Mou left us in a state of havoc and chaos. Well, what state is Ole leaving us in? Roses and sunshines?
As for Mancini, he's not leaving the WC so even discussing his appointment is pointless. Might as well say that Guardiola or Klopp would be good short term fixes or something. It's about as realistic.
