Chelsea scored in the 2nd minute thanks to Morgan Rogers. However, Arsenal successfully reversed the score thanks to two goals from Kai Havertz and Martin Odegaard.
In this match, Chelsea did not have the service of key midfielder Moises Caicedo even though he played in the 4-3 win over Brighton last week. Coach Xabi Alonso admitted to making a mistake for using Caicedo too early.
He said: "For Caicedo, it's not a long-term issue but a risk assessment. Perhaps, last week, we brought him on too early and I don't want to make the same mistake again.
After defeats, people often easily discuss the players they are lacking. I will not discuss that, I am satisfied with the players we have.
Surely all coaches have to deal with injuries, with suspensions. Having enough players for all matches is impossible. But Chelsea needs Caicedo and Colwill because they are top players and with them, we will be a stronger team.
Caicedo is a very important defensive midfielder for Chelsea. His inability to play has somewhat affected The Blues' game. Coach Xabi Alonso had to use Reece James and Lavia in midfield. Although they played hard and made many contributions, Chelsea's midfield still appeared inferior to Arsenal's very flexible midfield with Lewis-Skelly, Rice and Odegaard.
Despite losing the match, coach Xabi Alonso is proud of Chelsea's fighting spirit against Arsenal and hopes that the pain of defeat will add motivation for The Blues in the following months of the season.
For Arsenal, this victory continues to show the strength of the defending champion. They have won all 3 matches since the beginning of the tournament, leading the group convincingly.
This is the first time Arsenal has come back to defeat Chelsea in a Premier League match since October 2011 (5-3), ending a 14-match winless streak when they were led by The Blues (4 draws, 10 losses).
I think this is an excellent performance by Arsenal. I enjoyed every moment from beginning to end. We had a difficult start, but I really liked it because the whole team reacted spectacularly. I think it was also an exciting match for viewers, we deserved to win, that's what makes me happy," coach Mikel Arteta said.
