I don't think it's so certain other truly top clubs will be quite so anxious to recruit him now. What's he done this time? He's taken over a hugely expensive side that was already winning things, added a few more mega-signings, won the title without much style, then overseen the disintegration of that side, failed to develop promising young players, failed to reinvigorate his senior stars, and made an absolute tit of himself with the authorities, the media and even many of his own supporters. The scales have tipped now against him - it would be a top club doing him a favour more than the other way round, if the owners of such clubs have any real intelligence. Would a genuinely big club hire him to develop the youth set-up? No way. Would it hire him to deliver several consecutive years of stylish, trophy-winning seasons? Not really, without a huge risk. There are calmer, cooler-headed, more trustworthy managers around, with a younger generation fast catching him up. The schtick is getting over-exposed.
His best bet is to take a long break, act as if he doesn't need the hassle any more, allow the excuses and self-serving myths to develop via the few hacks who still adore him, and hope that a billionaire owner impatient for one good season turns to him.
