Arsenal put a sorry Everton to the sword in a thrilling 5-1 encounter at th Emirates. Here are five things we learned.
Ramsey loves playing against Everton
After recently returning from injury, Aaron Ramsey made his presence felt against Everton. The Wales international scored a hat-trick as Arsenal hit  Everton for five! Ramsey has scored six Premier League goals against Everton, the most he has scored against a single opponent in the competition.
He is the 20th different player to score a Premier League hat-trick for Arsenal, more than any other team has had in the competition. The talk before the match was all about the new signings but Ramsey showed that the old boys have still got it.
Everton still can’t win at the Emirates
Everton’s most recent defeat against Arsenal was the 12th time they have failed to win at the Emirates. The Toffees have played more Premier League matches at the Emirates without winning (12 – W0 D4 L8) than any other club.
Mkhitaryan makes his mark
It’s no secret that Henrik Mkhitaryan didn’t show his full potential at Manchester United but he is off to a flying start at Arsenal. He provided a hat-trick of assists, two for Ramsey and one for Aubameyang.
The Gunners tore Everton to shreds and Mkhitaryan was at the heart of their best-attacking moves. In his home debut, Mkhitaryan became the first Arsenal player to provide three or more assists in a Premier League game since Santi Cazorla (4) vs Wigan in May 2013.
An unhappy landmark for Sam Allardyce
Sam Allardyce became the fifth manager to manage 500 games in the Premier League, joining Arsene Wenger, Sir Alex Ferguson, David Moyes and Harry Redknapp. Of those five managers, Wenger is the only one who won his milestone game.
Aubameyang has a great debut
Pierre-Emerick Aubameyang signed for Arsenal on deadline day and immediately showed why he became their record signing. Aubameyang slotted into Arsenal’s attack straight away and could have had more than one goal. However, with the debut goal that he did score, he became the sixth player to score on his Premier League debut under Arsene Wenger.
