The game in London was hotly contested and ended up being an extremely exciting game at the end. We have to look at ourselves as well.
One player who will want to put this game behind him is Alvaro Morata.
Both Sanchez and Ozil have yet to come to an agreement with Arsenal regarding their future.
As we realised, that wasn't quite the case.
The furious Frenchman also insisted he would fight the FA charge levelled at him after he confronted Mike Dean in frustration after the official gave a soft penalty against Arsenal after he harshly adjudged Calum Chambers to have handled in the box after Kieran Gibbs fired the ball at him from close range. In the end the first half finished with a scoreless draw, but Arsene Wenger's men had a slight supremacy overall.
Key stat: Hazard's penalty was the first goal he's scored at the Emirates.
If anyone thought the second half was going to be slower, then they could not have been more mistaken. It was a game either side could have won had they taken their chances as both keepers were tested.
Chelsea's resistance would not last forever.
Since the beginning of the match, the game was full of excitement with attack and counter attack. However, when he is on top form, he is at the heart of Arsenal's best moves. And when Wilshere gave the Gunners the lead, fans couldn't sit comfortably, purely because they knew that Chelsea would be gifted a golden chance very soon. Arsenal looked dazed and confused, and The Blues looked in control after they scored.
Arguably the worst player for Arsenal on the pitch. He failed to convert two good chances for the home side, one in which he took a lot of time to sort his feet.
Danny Welbeck (Lacazette, 79) - 5 - Quiet after replacing Lacazette as the game opened. Even that they almost lost in the final seconds when Davide Zappacosta thumped the ball against the cross-bar.
It was a pulsating Premier League encounter, but was 0-0 at half time with the goals flowing in the second 45 minutes.
So much so that his loan to Bournemouth in the 2016-17 season was seen as the final act of his Arsenal career. Went down under a challenge from Bellerin in the box and duly converted the resulting penalty.
A few minutes later, Courtois was called into action at the other end with the Belgian shot-stopper producing a good stop to thwart Alexandre Lacazette from 12-yards out.
The game was far from over, though.
The Blues pushed for a victor and they eventually look the lead on 84 minutes, with Marcos Alonso clipping a low shot past Cech after great work from sub Davide Zappacosta. A weak effort aimed straight at Cech was followed by a thunderbolt courtesy of right wing back Zappacosta, who nigh-on dented the crossbar.
The Gunners continued to craft opportunities of their own.
