The Gunners went down 1-0 at the hands of Everton at Goodison Park which now means that Chelsea could overtake them if they beat West Ham United on Monday.
The Blues are currently fifth on the league table with the same number of points as Arsenal and a win over the Hammers would take Sarri’ men into the top four.
But the biggest concern for Arsenal right now will be with the absence of Sokratis after the defender picked up his tenth yellow card of the season.
This means the centre-back will miss the next two Premier League games – an away game vs Watford and then at home vs Palace.
Sokratis has been a key figure for Arsenal during the 2018-19 season and Unai Emery will surely be a bit tensed.
Emery favours a three-man defensive line but right now with Laurent Koscielny out of the picture, that tactic is basically useless.
The Frenchman is currently recovering from a bruised foot and given that Arsenal play their next game on the 15th, Koscielny should be able to make a return.
But with Sokratis out, we doubt if Emery will play three at the back.
In order to keep a backup defender, Emery might very well switch to a 4-4-2 during Arsenal next two Premier League games until Sokratis is eligible to play.
