Thierry Henry (NY Red Bulls, loan); Thomas Eisfeld (Borussia Dortmund, £400,000).
Any business Arsene Wenger conducted in the transfer window was always likely to be overshadowed by the return of Thierry Henry.
Exactly a month after a statue was unveiled in his honour as part of the club's 125-year anniversary celebrations, Henry was netting the first goal of his second spell at the Gunners against Leeds United.
Following a succession of rumours linking Arsenal with many of Borussia Dortmund's title winning squad of last season, supporters will have been disappointed to see the name of Thomas Eisfeld come through the door, rather than that of Mario Gotze or Lucas Barrios.
Emmanuel Frimpong (Wolves, loan); Vito Mannone (Hull, loan); Sanchez Watt (Crawley, loan); Daniel Boateng (Swindon, loan); Ryo Miyaichi (Bolton, loan).
Wenger will be hoping both Emmanuel Frimpong and Ryo Miyaichi can build on their first-team debuts during loan spells with Wolverhampton Wanderers and Bolton Wanderers respectively.
While Wenger will have seen enough of Frimpong during the first half of the campaign to suggest he has a future with the Gunners, particular attention will be devoted to Miyaichi's progression at the Reebok Stadium.
The Japanese starlet has made just two appearances for the club, and follows in the footsteps of Jack Wilshere.
Anzhi Makhachkala had reportedly expressed an interest in winger Andrey Arshavin prior to the window closing, but the Russian big spenders will have to wait until February 24th to complete a deal.
The Gunners were also thought to be interested in Watford's Adrian Mariappa, but The Hornets saw off the advances.
