Arsenal manager Unai Emery has defended his decision not to include Mesut Ozil in his matchday squad for the shock 1-0 loss against West Ham United in the Premier League on Saturday.

Declan Rice scored the only goal in the contest, and the Gunners played one of their worst matches of the season. They have taken just one win in their last four Premier League outings.

As Goal's Stephen Darwin reported, Emery confirmed Ozil's absence was not injury-related after the match: "I decided the players who are the best for this match. We win with him and lose with him. Not one player is for sale.He’s working this week normally. Like I said we win with him and lose with him. Today the decision is to come with these players."

Emery also left Aaron Ramsey, Lucas Torreira and Hector Bellerin out of his starting XI, with all three coming on as substitutes.

Ozil's absence was the main talking point, however, and the poor result continued a trend, per sportswriter James Benge:

Creativity was a major issue without both Ozil and Ramsey, and with the latter seemingly on his way to Juventus, the club is desperately short in that department, per Darwin.

Creating chances isn't the only issue plaguing the Gunners, however, as this statistic from Squawka Football shows:

After an excellent start to the season, things have quickly gone south for the Gunners. Manchester United have closed the gap between the two sides to just three points and could pull level with Arsenal if they beat Tottenham Hotspur on Sunday.

Chelsea will have the opportunity to increase their lead in the race for the final UEFA Champions League ticket against Bournemouth later on Saturday.

Sportswriter Adam Crafton believes neither Ozil nor Emery are responsible for the crisis at the Emirates Stadium, even if their "power battle" hasn't helped:

The Gunners' next outing will be the vital clash with Chelsea next Saturday. If the Blues beat the Cherries on Saturday and get the win at the Emirates Stadium, the race for the top four could well be over already.
