The scary thing about Mancini getting sacked is that City might stop underachieving.
Possibly or more likely someone will come in with a totally different idea about what they want and make a ton of multi million pound signings that will need more time to bed in and add to all the egos that like to ruck with eachother. Pellegrini is obviously a decent manager but I don't think that appointing a manager that has zero command of English is a good idea, especially at a club full of all those personalities and expectations.
