Fans and pundits alike have been calling for Arsene Wenger to spend this transfer window. With little time remaining and little to show, Wenger must be a busy man these coming days in order to bring in some talent.
After the sales of Samir Nasri and Cesc Fabregas, Wenger definitely has the funds. So whom should he buy?
Gary Cahill has been linked with a host of top clubs, with Arsenal and Liverpool originally the two pack leaders. However, little progress has been made in a move for the English International away from Reebok Stadium.
The 6'2'' Cahill leads the Bolton back line convincingly, and at 25 would not be against Wenger's "youth project."
Though a move would cost upwards of £10 million, Cahill could be tempted by the prospect of European football.
Okay, he isn't a Premier League defender anymore, but Scott Dann certainly deserves to be.
Although he hasn't played in a while due to injury, the Englishman has been linked with Arsenal almost all summer.
The 24-year-old helped form a decent partnership with Roger Johnson last season, and his January injury surely played a part in Birmingham City's drop last season.
With his clubs relegation and money troubles, Dann could be one of Wenger's cheaper options.
Phil Jagielka has been a integral part of Everton's defense since his £4 million move from Sheffield United in 2007.
Since then, Jagielka has become an English international and a well-respected defender in the EPL.
Arsenal have been reported to even have tabled bids for Jagielka, with Everton turning down a rumored £12 million bid.
Now that Wenger has surplus cash, a bid in the region of £15 could pry the 29-year-old away from Goodison Park.
The Fulham centre back was linked with Arsenal back in 2009, and maybe it is time for Wenger to renew his interest.
The captain of the Norwegian national team is a consistent performer, solid defender and offensive threat. Brede Hangeland scored six goals during the 2010-11 season, making Fulham's second highest goalscorer after Clint Dempsey.
At 6'4.5", Hangeland is a serious aerial threat and physical presence, something Arsenal desperately need. Additionally, the 30-year-old is well composed and experienced, which will help the young Arsenal defense to avoid further collapses.
Alex has seemingly dropped in the Chelsea pecking order, as he now apparently finds himself behind John Terry, Branislav Ivanovic and David Luiz.
The Brazilian rightfully is looking around for first-team options, and Arsenal have recently been rumored to be lining up a bid for the 29-year-old.
Alex is an imposing presence and possesses a rocket of a free kick, and would be a good pick-up for the Gunners.
Danny Welbeck's goal this past weekend highlighted the Gunners' lack of physicality in the heart of their defense. Who better to add physicality than the very person Wenger criticized?
Ryan Shawcross has made a career of being a hard-nosed, no-nonsense, tough-tacking defender. Just ask Aaron Ramsey, who was sidelined by Shawcross in early 2010.
Shawcross' 6'3'' frame will also help Arsenal in both defending and executing dead ball situations.
At only 23, Shawcross is the youngest on this list, but has shown composure beyond his years, which helped convince Tony Pulis to name the young Englishman Stoke captain for the 2010-11 season.
While bringing in Shawcross would certainly have a mixed reception, the Stoke defender would no doubt add some much needed grit to the North London side.
The 27-year-old Congolese defender has perpetually been linked with Arsenal all summer long.
Samba has been a consistent force at Blackburn since his January 2007 move from Hertha BSC, with his raw physicality a strong attribute and key factor in his success.
Despite signing a new contract in February, Samba has been repeatedly linked with a move to the Emirates.
Samba's 6'4'' frame and durability will ensure the defender won't break easily, and his leadership within the dressing room would certainly be a welcome asset in a relatively leader-less Arsenal side.
Leave a comment describing whom you think Wenger should buy, or other centre backs in the EPL or world football who could help boost this Arsenal side.
