Arsene Wenger has some major decisions to make on Jan. 31. Reuters

Arsenal appear to be on the verge of landing two players in the final hours of the January transfer window.

The Gunners are believed to be ready to make a bid for 25-year-old Watford defender Adrian Mariappa, according to the Sun. There have been differing reports over Mariappa's valuation, and it's possible that the full back might cost Arsenal roughly £2 million.

Mariappa would be a valuable addition to the Gunners, who have had injury woes this season at full back. Jeremy Wilson of Telegraph reported that Mariappa's arrival to Emirates is contingent on moving centre back Sebastien Squillaci, who has barely played this season.

There has been no speculation where Squillaci might end up.

Arsenal are also close to adding Thomas Eisfeld of Borussa Dortmund, according to sources. The 19-year-old attacking midfielder, who is out of a contract this summer, is expected to garner a bid of £600,000.

Sky Sports reported that Arsenal and Anzhi Makhachkala have begun talks over Andrei Arshavin. The Russian transfer deadline has three weeks remaining, so Arsenal don't have to rush out a deal for the struggling winger.

Arshavin, 30, has 18 months left on his deal and had been linked to returning to Russia over the past two months.

With Squillaci and Arshavin perhaps on their way out of Arsenal, manager Arsene Wenger appears to be doing a bit of a house cleaning. Alex Oxlade-Chamberlain has looked rather comfortable playing on the left wing.

Perhaps the big surprise in January is that Marouane Chamakh remains with the club. The Morroccan had been linked to a departure from Emirates for the past few months.

Meanwhile, Arsenal midfielder Ryo Miyaichi has joined Bolton on loan until the end of the season.
