Arsenal boss Mikel Arteta to BBC Sport: "The result is the main thing today, we really needed that win. We have been unlucky and frustrated with our results in the last eight weeks so this was a big day for us.
"From the first whistle you could see the team had the energy and willingness to come out and win the game.
"The spirit before the game was really positive, they really wanted it. I am pleased for the players and for the supporters, We have let them down for many weeks so it was a good day to give them something to cheer about.
"When we gave the penalty away I couldn't believe it - it's the magnificent game called football. It can always surprise you."
Chelsea boss Frank Lampard to BBC Sport: "In the second half we showed some urgency but it was too late. The first half we gave ourselves too much to do, we were very poor. You can't lack energy and desire in the Premier League and we did.
"You can prepare as well as you want but if you turn up like that that's another thing. It's in the mind.
"If you perform below par things go against you like the Saka goal. That's life. On another day we could have scored the penalty and come back but it's not a day for us.
"The teams that win, win, win relentlessly weren't winning two or three years ago. We are not there yet, that's clear. I felt it when we are on our long unbeaten run and I feel it now. We got a lot wrong today."
