Arsenal forward Alexis Sanchez rediscovered his goalscoring touch as his hat-trick ended Leicester’s unbeaten start to the season. Jamie Vardy had put the Foxes ahead with a superb finish from a tight angle after a clinical counter attack. Theo Walcott equalised when Leicester were themselves caught on the break. Sanchez then took control of the contest with his treble – the pick his third from long range – as Vardy and Olivier Giroud netted late on. Sanchez, who scored 25 goals last season for the Gunners, had failed to find the net in eight games across all competitions before this contest.

The result means Leicester are now without a win against Arsenal in 18 Premier League games, stretching back to November 1994. Following a relatively subdued start to the season, Sanchez showed his quality at the King Power Stadium. He scored his first goal of the term with a poacher’s effort when he tapped in from close range after good work down the right by Hector Bellerin. From the moment the ball hit the back of the net the former Barcelona forward’s confidence came flooding back. He appeared in dangerous areas, ran at defenders and it was inevitable he would add to his tally later in the game. Sanchez claimed his second with a header, with his hat-trick the pick of his three goals as he struck a low, powerful shot past Leicester goalkeeper Kasper Schmeichel.

Arsenal made an underwhelming start to the campaign – collecting four points from their first three games – which saw them written off as possible challengers to Manchester City and Chelsea. But the Gunners completed their victory over Leicester in plenty of style. Back was the attractive one-touch football as they cut through Leicester’s back line – albeit one that has now leaked 14 goals. Arsenal manager Arsene Wenger said Sanchez is now “back to his best” , and his side have now moved up to fourth in the table, just three points behind new leaders Manchester United.
