Arsenal manager Mikel Arteta to BBC Match of the Day: "It's a very special day for us. We knew the importance of the match and what it means to our fans. To be able to give them that joy, it's a beautiful day."
On Eberechi Eze becoming only the fourth ever player to score a hat-tick in the North London derby: "That tells you about the difficulty and what he's done today. To be fair he could have scored four or five. He's a big player who can create magic moments which unbalance a team.
"We dominated every part of the game. We created massive chances and had a lot of actions that we were very close to scoring. We stayed patient.
"Whoever we put in there they do the jobs for us. This squad has the belief and quality to deliver consistently.
"We have really good momentum but you can see how difficult every game in the Premier League is. It's a long run, let's go game by game. Let's enjoy tonight, then we have Bayern here and Chelsea away. We have a tough week."
Midfielder Eberechi Eze to BBC Match of the Day: "That is crazy. Special day, man. Special day for me, my family.
"I don't think I could've ever dreamt of it. This is more special than that. I can only thank God. Special day, man.
"We were prepared for whatever set-up they were coming with because of the diligence of our staff. Huge credit to them. And of course, the players in our team, the ability, the talent, from whatever angle we're threatening to score goals.
"Good performance, good three points and a special day.
"I probably should've scored four, to be honest. I'm always trying to score, always trying to take my chances. It's important to be relentless.
"We're focused on ourselves, we're focused on putting in our work every day. It's not by chance that we perform like this."
