#2 Everton make unwanted history
For all of Arsenal's brilliance in this match, Everton were simply disastrous, conceding three goals inside the opening 20 minutes, before lasting only 18 minutes before letting in a fourth. Manager Sam Allardyce, who prides his side on being tough to beat wouldn't have been impressed.
That poor first half for the Toffees saw them make unwanted history by conceding four goals in the first half of a Premier League match for the first time in their history.
The fourth goal may have been harsh on them, given that Aubameyang was offside, however, looking back on the first three goals, Everton will not be pleased with the amount of space each scorer was given to convert their chance and should put in more compact performances in defence, if they are to avoid another big beating.
