Buying Otamendi and Navas weren't cock ups at all.Buying Bony, Mangala, Fernando, Nolito, Bravo, Otamendi, Navas.
Even players like Stones and Sterling have much to prove.
Selling Dzeko, Tevez and Negredo.
Allowing all 4 full backs to get over 30 years old and then releasing three of them at once without sorting out replacements.
Appointing then retaining an average manager for 3 years.
Need I go on?
Selling Dzeko and Negredo neither. Selling Negredo was extremely good business.
