Ancelotti shouldn't of been sacked, I think, although he was not that good, as people suggest. He is a good manager, though, and can bring stability - and trophies - in the long term, I believe. Roman Abrahmovic doesn't understand football, and has made some poor decisions in recent years. I'm thinking José Mourinho or Andre Villas-Boas to take over if Chelsea are willing to wait for a 'big name' manager, or maybe Paciencia (Braga coach, unlikely though) or they may poach a manager from a 'smaller club' for a sum of money.
