Saturday marks the final Manchester derby of the decade, and it has been a tumultuous 10 years for both City and United.
It began with United as the kings of Manchester and the dominant force in English football and with City on the rise following Sheikh Mansour bin Zayed al Nahyan's huge investment after his 2008 takeover.
As we approach the 2020s, City have become Manchester's top team, with four Premier League titles this decade, and United have been on a downward spiral since Sir Alex Ferguson's retirement in 2013, also the last time the Red Devils finished above their rivals in the league table.
