Arsenal were in sixth heaven on Wednesday night as they dismantled Ludogorets Razgrad in a ruthless Champions League display which saw Mesut Ozil scoring a hat-trick after stunning goals from Alexis Sanchez and Theo Walcott.

Sanchez got the first with a masterful chip from just inside the box.

Walcott powered a curling shot home after Ludogorets’ Wanderson hit a post.

Alex Oxlade-Chamberlain smashed a loose ball into the corner for the third, before Ozil scored three times in a game for the first time in his career.

The Gunners have won seven games in a row in all competitions – scoring 23 goals – and are undefeated in eleven matches.

Their last defeat was at home to Liverpool on the opening day of the Premier League season.
