Now, in 2016, we are set for a heavyweight rematch, this time between footballing giants Jose Mourinho and Pep Guardiola, who from their respective offices – just five-and-a-half miles apart – will be planning their knockout blows.
And come August 13, supporters of both Manchester clubs will be ready to settle back, crack open the beers and enjoy a ding-dong fight for Premier League supremacy.
Let battle commence.
In an unprecedented move, Guardiola will be unveiled to the City faithful a week today when 11,000 fans will pack into the club’s Academy stadium, where they will experience a glittering array of firsts – the first sighting of their new boss, their new badge and their new kit.
Ilkay Gundogan – the Spaniard’s first signing – will be on show, too, as Guardiola takes to the stage to answer fans’ questions.
