David Moyes knows from personal experience that honeymoon periods can be painfully short in Manchester.
Fate brought him back to town for his first Premier League game since he was unceremoniously sacked by Manchester United in April 2014, and Sergio Aguero duly brought the bad memories flooding back less than three minutes into his return as manager of Sunderland.
It was the Argentine who scored twice when City destroyed United 4-1 here a little over a month into Moyes’s ill-fated tenure at Old Trafford. So Moyes could have been forgiven for fearing the worst last night, and even more so when he witnessed the familiar sight of Aguero wheeling away after scoring so early.
