Here's all the news from around the Emirates Stadium over the past 24 hours.
Arteta makes Aubameyang prediction
Mikel Arteta believes Pierre-Emerick Aubameyang’s confidence will be lifted after breaking his goal drought against Manchester United.
Arsenal claimed a well-deserved 1-0 victory at Old Trafford, with Aubameyang scoring his first goal since the season-opening win against Fulham.
And Arteta is pleased that Arsenal’s captain and chief goalscorer has broken his duck.
“I’m glad it’s finished. Every striker needs goals and in these moments we have to create more for Auba,” said Arteta.
“He has scored the crucial goal and it is going to lift his confidence. Added pressure because he knew how crucial it was for us to win today. He took it really well and I'm really happy for him.”
Partey tipped to emulate Vieira
Roy Keane says summer signing Thomas Partey can emulate Arsenal legend Patrick Vieira after an excellent performance against Manchester United on Sunday afternoon.
“Brilliant,” Keane said on Sky Sports when asked about Partey’s showing. “We said before the game, this guy is no mug, he's played at big clubs, in big competitions and we saw it today.
“When you watch a player live - that’s when you can judge a player. The more I look at him, I wish he was in Man United’s midfield; big, strong, and aggressive.

“I go back to my battles with Patrick Vieira, I think this kid’s got a chance of matching what Patrick used to do because he’s big, he’s strong, he’s aggressive, and he likes to pass a football forward.
“He can deal with the ball, he looks comfortable on the ball - just little details - a bit of composure, good first touch and retaining possession, that’s the aim of the game.”
Neville picks out Arsenal’s star performer
While Partey was showered with praise for his performance – and Mohamed Elneny impressed after his surprising start – Gary Neville named another new star as Arsenal's best performer at Old Trafford.
Speaking on Sky Sports after the victory, the pundit hailed the impact of centre-back Gabriel Magalhaes, who was signed from Lille in a £27 million move this summer.
“Arsenal’s defensive performance has been brilliant, from front to back, but the back-three have been good," Neville said on commentary. “Gabriel has been fantastic, so far I’d say he’s been the best player on the pitch, for me.”
Neville added: “Arsenal absolutely deserved that. He was brilliant, Mikel Arteta, in the way in which he set his team up.
"Aubameyang got the goal, which his team deserved. It leaves Manchester United in a desperate position, but he (Arteta) won’t care about that.
“He’s won the day, and deservedly so.”
