A title push had threatened to fall away when Gary Cahill struck to give Chelsea the lead at the Etihad Stadium on Wednesday night. However, Sergio Aguero's penalty put things back on track before Samir Nasri's 85th-minute finish capped off an incredible turnaround to keep Manchester City only one point away from the summit of the Premier League table.
The Frenchman's strike was not only a crucial blow landed in the fight for the title - it also sealed an incredible record of 20 consecutive wins at home, the first time that such a feat has been achieved in the English top flight.
Roberto Mancini has led his troops through a highly successful period, leading the way in the standings for most of the 54 weeks over which they have maintained this astonishing run of form.
It is a record that has seen City blitz 56 goals and concede just eight, a fearsome statistic of which any side in the world would be proud, and Goal.com took it upon itself to relive the brilliance of Mancini's record-breakers at the Etihad Stadium.
