Poor defense, especially Mustafi’s mistake (red and white), caused Arsenal to lose this time.

Goals: Ozil 47′, Aubameyang 77′ – Benteke 17′, Zaha 61′, McArthur 69′.

This should have been a beautiful week for Arsenal.

That’s probably the reason coach Emery decided to put defenders Konstantinos Mavropanos and Carl Jenkinson on the field from the start.

Those choices, at first, seemed reasonable – especially in the context of the extremely important front, the Europa League.

Benteke headed the opening goal for Palace.

But the naked truth is gradually revealed.

And the consequence was Arsenal’s losses.

After the break, Mavropanos and Jenkinson were both replaced.

Ozil held on to the hope of scoring points for Arsenal but failed.

Those mistakes ruined all the efforts of the players on attack – especially Ozil.

That was the most exciting and powerful time for Arsenal in this match, after coach Emery decided to change personnel from the beginning of the second half with the presence of Alex Iwobi.

Created many opportunities after that, but Arsenal could not score any more goals.

This defeat caused Arsenal to continue to rank fourth with 66 points – equal to Chelsea, and one point less than Tottenham.
