Having not previously scored this season, the Chile international excelled with three goals at the King Power Stadium, with Theo Walcott and Olivier Giroud also finding the net.

The last unbeaten record of the Premier League season fell on Saturday as Arsenal came away from the King Power Stadium with a 4-1 victory over Leicester City, Alexis Sanchez roaring back into form with a hat-trick. Claudio Ranieri’s side took the lead early in the game when Jamie Vardy was released down the left and fired home froma narrow angle but Theo Walcott exploited his pace to equalise just five minutes later.

Alexis finally scored his first goal of the season to see the Gunners through to half-time with an advantage and the Chilean followed up just short of the hour when he headed in from Mesut Ozil’s cross.

The Arsenal forward then sealed his hat-trick in the 81st minute, skipping inside a defender to shoot long and low into the bottom corner from 25 yards.There was a consolation for Leicester late in the day when Vardy scored his second of the match, a curling finish after Arsenal failed to properly clear the ball, but there was no question that the Alexis-inspired visitors were going to lose control of the result. That much was confirmed when Olivier Giroud swept in a fifth for Arsene Wenger’s men at the death.
