Winner: Eddie Nketiah
Nketiah seized his opportunity to impress from the start, just as he did against FC Zurich in the opening Europa League group stage game.
The 23-year-old has now scored in both his starts this season and continues to show an all-round game that looks much improved on what we've seen from him in previous seasons.
He looks strong, direct and is holding the ball up impressively well.
His finish, after Kieran Tierney's shot had come back to him off the post, was very sharp.
The form of Gabriel Jesus is making things difficult for Nketiah in the Premier League, but if he continues to perform like this when he does get a chance then it won't be long before he gets more minutes.
Winner: Rob Holding
You could see the delight in Holding's face when he scored.
The Arsenal defender has struggled for any sort of game time this season, so it was no surprise to see him smiling when he planted Fabio Vieira's excellent cross into the corner to make it 2-0.
Holding is very much fourth in line now at Arsenal when it comes to centre-backs and he understands that.
But it's still been a frustrating season for the 27-year-old, so he would have been determined to make an impact on what was his first home start of the campaign.
And he did exactly that, marshalling the defence well and getting himself on the scoresheet.
Winner: Fabio Vieira
What a talent the young Portuguese playmaker looks.
Vieria has impressed every time he's taken to the field this season and tonight was no different.
There are still some flaws in his game, which is not surprising given his age and inexperience, but the 22-year-old has so much potential and quality on the ball.
His whipped cross for Holding's goal was excellent and he was then on hand late on to score his second for the club after some fine play from Gabriel Jesus.
The goal capped a wonderful performance from the attacker, who looks like a £30 million bargain.
Mikel Arteta predicted that the Arsenal fans would enjoy watching Vieira when he got fully fit and, judging by what we've seen so far, he was not wrong.
