There was a banner draped at the Etihad Stadium one sunny afternoon last May, as tears and champagne flowed in equal measure. 'Thank you, Sergio. You changed our lives.'
And he did. Sergio Aguero was more transformative than any other single player to have pulled on a Manchester City jersey over the last decade. David Silva's grace and Vincent Kompany's leadership run him close but it is not really a contest. The trio will stand together immortalised at City's home when Aguero's statue is finished next year.
The day he bid farewell to the east of this city will live long in the memory of those 10,000 lucky enough to snaffle a ticket.
