Two moments stick out in recent memory on this day in Manchester City history.
On this day in 2012, Borussia Dortmund arrived at the Etihad Stadium during their golden era with Klopp in charge, and the likes of Robert Lewandowski, Ilkay Gündoğan and Marco Reus among their stars. And to put it bluntly, they completely outplayed City and but for the heroics of Joe Hart, could have put six or seven past us.
However, after going 1-0 down to a Reus strike, Neven Subotic handled the ball inside the area, and substitute Mario Balotelli, with ice in his veins, coolly scored the resulting penalty. City’s 17-game unbeaten run in Europe was thus preserved in slightly fortunate circumstances.
Fast forward three years to 2015 and we saw a Sergio Agüero masterclass at the Etihad Stadium as the Argentine hero struck five goals past Newcastle in the space of 20 minutes. Aleksandar Mitrovic nodded Newcastle in front, but from the 42nd minute to the 62nd minute, a flurry of goals by Agüero, plus a Kevin De Bruyne strike, meant City came out 6-1 winners at the Etihad.
Agüero deservedly received the match ball and in an iconic image, was snapped kissing it in mid-flight.
