Yaya Toure. Vincent Kompany. David Silva. Sergio Aguero.
For the last four summers in succession, Manchester City have waved an emotional goodbye to a club legend, a player integral to them becoming the super club they are today. This year it could well be a fifth but, instead, everything possible should be done to buck the trend and keep Fernandinho at the Etihad.
The City stalwart is now into his ninth season in the Premier League and, just like it was last year when he signed a one-year extension, his contract is currently set to expire in the summer. City have done such a good job in recent years of knowing when it's time to say goodbye to defining players when other clubs would become attached and allow to deteriorate at the top level.
