Arsenal are reportedly making progress in their efforts to land West Bromwich Albion defender Jonny Evans, while wantaway Gunner Mathieu Debuchy has been linked with a move in the opposite direction.
The Sun reported West Brom manager Alan Pardew has opened up to a January sale as he looks to make reinforcements of his own, and Arsenal are said to be "on the verge" of a £25 million deal (h/t Metro).
The Gunners have endured some defensive troubles of late, with the younger likes of Calum Chambers and Rob Holding failing to nail down spots, while the more senior Laurent Koscielny, 32, has been out of form for patches of the current campaign.
