Newcastle United boss Eddie Howe insists they deserved victory over Arsenal.
Anthony Gordon proved the matchwinner after three VAR checks.
Howe said, "Tough game. Massive win, full credit to players for what they gave today it was a battling performance. Both sides good but maybe not in ways we're both known it was a midfield scrap, physical and a lot of duels and thankfully we came out on top.
"Our open play shape defensively was good and has to be against Arsenal. We nullified them and didn't give them clear cut chances. I always felt we were in the game the other way, we had to stay in the game and we did and then got the goal.
"Maybe not the game we expected it to be in terms of style from both teams. Midfield battle was important, we had to try and stay in the game in that way and Joelinton was huge and all three midfielders really helped us. When you don't concede you're always in a game. It wasn't the game we prepared for but you have to show different sides of your game to win and I think we have that in the group at the moment."
On Gordon, Howe also said: "He's got used to what's expected of him. He had sight of it at the end of last season, he came back fitter from the Euros that was successful for him. That helped his confidence and he's been brilliant for us this season. And he's shown versatility.
"A marker of our mentality at the moment and willingness to win and there was a good feeling in the stadium. The crowd were responding to us and the players understood how important every tackle and duel was. You don't win these games unless you compete. Really proud, we're stretched at the moment but the players have stepped up.
"We have a group of level-headed players. The injury situation is a concern, it's a worry when you're competing on lots of fronts. At the moment we seem to be losing a player a game which is the big negative today. We'll let the dust settle on today's game and see what we've got for Dortmund."
