How fitting that Sergio should end his City career in much the same way as he began it; coming on as a substitute and scoring two goals at the North Stand end of the ground.
He has scored some important and brilliant goals at the other end - and elsewhere - but he will forever be associated with another he put away at that end, in what was the most iconic moment in Manchester City's history and one of the most memorable in world sport.
Am I right in thinking that he scored five on three occasions; Newcastle, Tottenham and Leicester? In his prime, he was a goal machine and, as his record shows he will always be remembered as one of the greatest goalscorers of all time. Will his minutes per goal record ever be beaten? I very much doubt it.
Thanks for all the fantastic memories, Sergio. There are too many to list them here, but I will never forget that sunny afternoon just over nine years ago, which wrote your name into Manchester City and English football legend.
