It was a victory to regain their authority in the title race.
Arsenal went five points clear of Manchester City at the top of the Premier League with another impressive win to prove they are in for the long haul.
Gabriel Martinelli scored twice to take his tally to 11 goals in the Premier League this season while Bukayo Saka also reached double figures after his opener sparked the rout. Saka must now be a big shout for Player of the Year, Martinelli is unstoppable in this form and they outclassed Everton so badly that the match looked more like a training session by the end.
