Arsenal extended their lead at the top of the Premier League to a formidable eight points with an outstanding performance and win in the north London derby at Tottenham.
The Gunners took full advantage of Manchester City's loss at Manchester United on Saturday with an impressive show of style in the first half and steel after the break to claim a vital three points.
Arsenal were helped by a blunder from Spurs keeper Hugo Lloris when he fumbled Bukayo Saka's cross into his own net after 14 minutes, but it was no more than Mikel Arteta's side deserved as captain Martin Odegaard drilled in a second from outside the area nine minutes before the break.
Arteta later said, "Very emotional. It is a very special day for everybody who feels the way that we feel about this football club. We talked about the opportunity and that we have to play with a level of enjoyment because we have the power to make people happy. I'm sure we made them proud and very happy tonight.
"To play in this stadium against this team with the courage, the determination, the quality that we showed, it was very impressive from the boys. But we showed the other face when we had to dig in, we needed some big moments from Aaron [Ramsdale].
There were some great defensive moments as well to do that and it's a shame because we didn't capitalise as well on another two or three big chances that we had. But overall, happy about the performance and the victory.
On goalkeeper Aaron Ramsdale making the difference, he added: "He was the difference when we needed him. In the opponent's box, we didn't finalise the actions as well as we should have. They have the quality, when you look at Tottenham's front three - that is always in the back of your mind."
On being eight points clear, Arteta concluded: "It means that the way we are playing has taken us this far and we should never forget that. We have to continue playing this way or better because the team still has a lot of things that can be improved collectively and individually and if we focus on that, I'm sure we'll be fine."
