It was sort of the perfect hat-trick: a header, one with the right foot, one with the left, er, elbow. Still, that it not what will be concerning historians in the years to come.
This was the 14th hat-trick of Aguero’s Manchester City career, and his tenth in the Premier League – bringing him one short of Alan Shearer’s record of 11.
How good is that? Well, put it like this, as it stands Aguero has scored as many hat-tricks as Cristiano Ronaldo, Didier Drogba, Mo Salah, Eden Hazard and Romelu Lukaku – combined.

Take Lukaku out and put Steven Gerrard in, and he’s got more. This is a phenomenal, match-winning, title-winning goalscorer. Will he win the title again this year? It won’t be for want of trying.
Aguero’s hat-trick wasn’t spectacular but it was the striker’s art encapsulated – yes, even the one that shouldn’t have been allowed. Raheem Sterling cut the ball back, Bernd Leno pushed it – he should have gathered it, no doubt of that – and Aguero bundled it over the line.
It touched the top of one leg, his flank and most crucially an elbow, but Martin Atkinson let it stand. Arsenal will feel aggrieved at that but it is unlikely to have made much difference to the outcome.
City were comfortable by then – so comfortable that when Arsenal’s new signing Dennis Suarez came on, Pep Guardiola took four steps sideways to pat him on the back and wish him well. You don’t do that if you’re greatly worried.
Of all the goals scored in the first minute since the inception of the Premier League, 1.4 per cent of them have been scored by Sergio Aguero in the last six days.
