Arsenal were expected to sign a few players in the January transfer window anyway, but they have already agreed deals with West Ham and Hannover for Chamakh and Djourou until the end of the season. With Squillachi and Arshavin also expected to leave, either permanently or on loan, Arsene Wenger has even more options and wages to play with.
If Squillachi does leave, it will allow Wenger to sign two top quality defenders, and the German international Benedikt Howedes is likely to be one of them. The 24-year old captain of Schalke has halted the talks he was having with the German club about extending his contract which runs out in 2014.
This could be a sign that Arsenal are closing in on the cultured centre back they have been tracking for some time, according to Talksport. He is highly rated in Germany and already has 10 full international caps after getting 22 at under-21 level. However, if Arsenal are only looking to sign one defender, it is more likely to Mapou Yanga-Mbiwa, because his versatility means he can play any position along the back four.
