But among all the drama were two puzzling moments as first Carlos Tevez then Samir Nasri celebrated their goals by revealing T-shirts with baffling words written upon them.
So what did those messages mean?
First up was Tevez, whose shirt read "Lugano 1 y 2", which was apparently a reference to the apartment block in which he grew up in Buenos Aires.
It was a natural progression from the T-shirt he displayed after scoring in the charity shield, which read "Fuerte Apache" in reference to his old neighbourhood. He'll have to up the ante again next time: his specific apartment number is an obvious next step then we can probably expect messages like "bedroom at the back" or perhaps "bottom bunk".
As for Nasri? Well, Sunday saw not only the beginning of City's defence of their title, but also the Muslim holiday of Eid ul-Fitr which marks the end of Ramadan.
Nasri, who is of Algerian extraction, decided to celebrate with a T-shirt message saying "Eid Mubarak", which is usually translated into English as "blessed festival", and is the traditional greeting given by Muslims to each other on the Eid ul-Fitr holiday.
