Goals from Pepe, Aubameyang, Ozil and Lacazette ensured a comfortable win for the Gunners at home.
Steve Bruce will be thoroughly disappointed with his team’s performance at Emirates. Arsenal were favourites to win the game from the start but Newcastle could have put up a better fight.
Newcastle are currently 13th in the table with 31 points. If they want to secure a top-half finish, they will have to work harder and improve in front of the goal.
The Magpies seemed toothless in the final third and it will be interesting to see if Bruce can turn it around in the upcoming weeks.
