Well, we know how long Denilson has wanted out for.
Bendtner has always wanted out, the best striker in the world should be at the best/biggest club in the world, we are not ergo he should be moving on.
I reckon Clichy has seen the writing on the wall for at least a season now, I'm sure he wanted/wants to stay but knows that there's a groundswell of opinion against him and I doubt it's purely on the side of the fans.
Bottom line is that the players failed to step up at the crucial part of the season, manager must take a hefty amount of responsibility for buying the wrong guys/not developing them well enough but if their name isn't Jack or Robin then chances are they're part of the reason we lost so fuck 'em.
