Aaron Ramsdale: Arguably lucky with the penalty and poor to concede at his near post from Maddison's strike. Could do nothing about Saliba's own goal, but he was not as solid as he was last week. 6.
Ben White: Solid enough down the right-hand side. Leicester struggled to get much joy there, with most of their attacks coming down the left. 7.
William Saliba: Really unlucky to let the own goal go in off his outstretched boot, but he hardly put a foot wrong aside from that. Another assured display. 7.

Gabriel: The more solid of the two and did well to cover generally when Zinchenko powered forward. Might have done more to stop the Maddison goal, though. 7.
Oleksandr Zinchenko: Offensively excellent as he supported Gabriel Martinelli and combined beautifully with Granit Xhaka. Defensively there are still a few question marks over his positioning, which mean Tierney will fancy his chances of getting back in. 7.
Thomas Partey: Some incisive passing in the middle of the pitch, including one eye of the needle pass to Xhaka in the first half. Defensively decent. 7.
Granit Xhaka: A complete midfield performance from the Swiss, who were defensively astute but also got forward stupendously to help the attack. The goal was a highlight, but some of his passing was sublime. 8.
Martin Odegaard: Again, maybe not as influential as he might have hoped, even if he was secure in possession. Perhaps a symptom of Arsenal's attack being so focused on the left. 6.
Bukayo Saka: Another who suffered from the left-sided bias of Arsenal's attack. Given the free-flowing nature of Arsenal's attacking display might have wanted to get involved more if possible but didn't do anything wrong. 7.
Gabriel Jesus: The kind of display that shows us again - not that we needed much reminding - why the Brazilian is such a good signing. An elite goal for his first and a poacher's finish for his second. Two assists on top of that as well. 9.
Gabriel Martinelli: The Brazilian is on a run of form at the minute that has really nailed him that left-wing spot down. He combined so well with Jesus and has an end product this season to boot. 8.
Substitutes -
Takehiro Tomiyasu: Steady in possession and defence while also contributing to the attack. It's good to see the Japan international back. 7.
Kieran Tierney: Shut most of Leicester's threat on the left-hand side down after coming on. Looks really defensively solid. 7.
Emile Smith Rowe: Came on too late to influence the game. n/a.
Eddie Nketiah: Came on too late to influence the game. n/a.
