Squad deficiencies addressed - and with a top-quality player too
Going into the window it was clear that Arsenal needed an attacking midfielder and a back-up goalkeeper. They finished it having signed both.
The arrival of stopper Mat Ryan on loan from Brighton signals a shrewd piece of business from Arteta and technical director Edu.
Despite only arriving in the summer, it has quickly become clear that Alex Runarsson is not up to the required standard and should Bernd Leno get injured they would have been in serious trouble.
Ryan arrives with Premier League experience and during his three years with the Seagulls, he has proven himself to be a reliable goalkeeper at this level. Just what you need in a good back-up goalkeeper.
Although, as we've seen only this week, it can be a gamble drafting in a No2 if he picks up an injury, which is what happened to Arsenal's Australian netminder, which kept him out of the squad for the Wolves game. Speaking of Australia and gambling, why not have a punt with Australia online casino.
As for the signing of Martin Ødegaard, this is one Arsenal fans should be very excited about indeed - even if it is only on loan.
Some will remember the Norwegian as a 15-year-old prodigy wanted by every top European club. He chose Real Madrid, and although he's struggled for game time at the Bernabeu he is beginning to come good on his potential.
Ødegaard shone in Holland with Vitesse Arnhem in 2018/19, before impressing on loan once again at Real Sociedad last season as he won La Liga's Young Player of the Year award.
A mercurial talent capable of opening up defences and changing games, the 22-year-old could have a big impact on Arsenal's season.
The Gunners have been criticised in the past for not addressing the issues in their squad and not acting quickly enough, but this looks to be a thing of the past now.
Big earners gone
When Arteta was appointed, he spoke of being ruthless, and that's exactly what he was last month.
Mesut Ozil, Sokratis and Shkodran Mustafi have all gone permanently, while Sead Kolasinac has left on loan. Arsenal have been trying to clear the decks of their ineffectual big earners for some time and it seems they've finally done just that.
With that quartet gone, and Matteo Guendouzi and Lucas Torreira also likely to leave permanently in the summer, Arsenal will have freed up more that £700,000 from their weekly wage bill.
That should be more than enough to help with a summer rebuild as Arteta looks to build a squad to lead his revolution at the Emirates.
Loans for those who needed them most
It was clear that Joe Willock and Ainsley Maitland-Niles needed regular Premier League minutes, and Arsenal have found them loans that will help them get just that.
With Willock off to Newcastle and Maitland-Niles headed to West Brom, both should become regulars as the two clubs look to battle relegation.
As well as the minutes, the scrap at the bottom should help with their development and maturity.
The Gunners have high hopes for the pair, but they must now kick on in their development if they want to become regulars at the Emirates. Their respective loan moves should help them do that.
The same could certainly be said for Reiss Nelson, and the only criticism of Arsenal's transfer window is the failure to secure him a loan move as well.
