Arsenal 2-0 Chelsea: Talking Points and Observations | Premier League 2018-19

#2 Four-man backline worked wonders for Emery, Koscielny brilliant

Koscielny is proving to be a much superior partner for Sokratis than Mustafi.

Ever since his arrival, Emery's biggest problem at the Emirates has been his defense. Though they improved a lot offensively, they struggled at the back.

The Spanish manager experimented with a back three on quite a few occasions this season, to varying effect, but opted for a well drilled 4-3-3 with Aubameyang and Ramsey flanking Lacazette, being supported by bombing fullbacks, Bellerin and Kolasinac.

Sokratis and Koscielny put in an excellent shift, keeping Hazard & Co quiet for the entirety of the match. The Arsenal centre-back duo never gave them space or time to dictate play. Laurent Koscielny was brilliant on the night and produced a Man of the Match performance. Sokratis supported his partner well and had a good game.
