Arsenal's winning streak came to an end as they were held 2-2 by Crystal Palace on Sunday afternoon.
The Gunners fell behind after Luka Milivojević converted from the penalty spot just before half-time.
Arsenal fought back and took the lead after Granit Xhaka and Pierre-Emerick Aubameyang notched for the visitors.
It looked as if Arsenal would hold on to preserve their winning streak to 12 games, only for Milivojević to score his second penalty of the game seven minutes from time.
Neither side could find a winner and so the game ended in a draw.
Unai Emery admitted after the game that the result was fair on both teams.
“This draw is just because the teams deserved, a minimum the draw," he said, per the Independent. "We were in control when they scored their first, not doing a lot in the attacking third, but in control of the match.
"In the second half we scored two goals from two individual actions and then, a lot of minutes on the games for holding this result with them pushing, with their supporters, and every player attacking us.
“In this moment, we needed the control because we lost possession. We needed to score the third goal to be calm.
"But we cannot do good chances for this and, when they drew, I think... I want to push, to find a moment for us to win the match, but we cannot. This draw is what both teams deserved.”
But not everyone in an Arsenal shirt was happy.
Mesut Ozil was hooked off in the 68th minute and proceeded to throw his gloves on the ground in anger.
Although Aubameyang did not show the same anger when he was taken off 10 minutes later, his social media activity suggests he wasn't too happy with the decision.
Arsenal's official Twitter account tweeted after the game a rather impressive stat about Aubameyang: "He has scored all of his last six shots on goal in the Premier League."
That led to a fan complaining about the decision to take him off. Twitter user @rajamudaikhsan replied: "Then why are you replacing him? Why not let him score again? #YaGunnersYa"
Instead of acknowledging Arsenal's tweet, Aubameyang retweeted the fan's post complaining that he had been taken off.
This got Arsenal fans talking, with many believing he was unhappy with the decision by Emery to take him off.
It will be interesting to see if more in regards to this retweet develops in the future.
