Arteta said that it was still far from perfect.
We had some good times. We gave up too many chances in the second half. It's not easy to win here and there are still things to prove.
The game started well for us. We were the clear leader. We had a lot of faith in the two goals. The goals were scored by Jesus. His contribution was great.
Arteta said there were areas of the squad which still needed more firepower before the end of the transfer window, but any signings would not be made for the sake of it.
Arteta said that they want to get the players that they think will make a big impact.
We will attempt to do that if we can. We will keep the players we have if we can't.
We know where we need to add more firepower. We'll do it if we can.
Gabriel Martinelli was the beneficiary of Jesus' pass in the fifth minute. The forward's shot was saved by the goalkeeper but he was able to score.
After a low cross from Ben White, Odegaard took advantage of more intelligent movement from Jesus to score his second goal and put the game out of reach.
The team clicked through the gears in the first half and the fans were in a good mood as they watched from the sideline.
William Saliba scored his first goal for the club in the 54th minute when he swept a cut-back from Martinelli into the net.
Jesus looked to have put the game out of reach in the 72nd minute when he latched on to a clever pass from Odegaard, but it was ruled out for being off target after a VAR review.
Odegaard said that Jesus is more than just a goal. He drops down to combine in the play.
He is a great player and brilliant. We're fortunate to have him here.
The Cherries had a chance to get back in the game in the 78th minute when Kieffer Moore rose to meet a cross, but Ramsdale made a great save.
We are a little bit ahead compared to last season, but we have to stay calm and not get carried away.
