Danny Ings took advantage of some typical Arsenal defending to give Southampton the lead at the Emirates on Saturday afternoon.
The former Liverpool striker scored on the counter-attack early in Saturday's clash at the Emirates, leading to more frustration from Gunners fans.
Emery fielded a surprisingly defensive side that comprised five defenders in Calum Chambers, David Luiz, Hector Bellerin, Sokratis Papastathopoulos and Kieran Tierney.
Matteo Guendouzi and Lucas Torreira were in midfield with Mesut Ozil playing in behind Pierre-Emerick Aubameyang and Alexandre Lacazette.

But Arsenal's seven defensive players all stopped and were caught napping from a quick free-kick by Ryan Bertrand.

And a grateful Ings slid the ball in at the near post past Bernd Leno to open the scoring, much to Arsenal fans' frustration.
The Emirates faithful have grown restless in recent months with calls for Emery to be sacked, and this latest defensive horror show didn't help.

Arsenal needed an injury-time equaliser from Lacazette to rescue a draw against the Saints.
The Frenchman cancelled out Southampton's early strike in the 18th minute, but James Ward-Prowse looked to have earned the visitors all three points with 20 minutes to play.
Lacazette equalised for the second time, though, in the 96th minute to spare Emery another embarrassing defeat.
