All utter nonsense. Zabaleta has been a constant presence in an Argentina side that got to two consecutive major finals in recent years, and Demichelis started in the latter stages of both tournaments as well. Both were solid for City last season and showed no real signs of decline. Clichy might not be the best full back but the one thing you can't call him is a clown, he's typically very consistent defensively. Toure's season last year was not his best, no denying, but saying he regressed massively is ridiculous hyperbole (the guy had an excellent period of form before the AFCoN and then captained his side to victory in that very competition) and claiming he only has attacking influence means you clearly have some misguided opinion of his style of play. He was still one of the league's better midfielders last season.
However, I'll let you have Kompany is past it and Mangala is a clown, even if they're exaggerated points
