Arsenal may have to enter the market for a right-back this January.

Calum Chambers and Francis Coquelin have both played in the position before, but Arsène Wenger could want a more experienced understudy to Héctor Bellerín as we approach the last few months of the season.

Until now that man has been Mathieu Debuchy but, agitated by a lack of games and eager to get back in the France squad before Euro 2016, the 30-year-old looks likely to be granted his wish to move before the season is even over. Arsène Wenger confirmed in Wednesday’s press conference that the defender’s time in north London may be up just 18 months after it began.

Alerted by the news he could be available, AS Roma and Lyon are reportedly interested in signing him. This comes after links to West Brom, but maybe playing for a more prestigious club abroad is what he would be after as he looks to force his way back into the national side.

The way Debuchy has performed when selected this season has been subpar. Games against West Ham United, Tottenham Hotspur, Sheffield Wednesday and Bayern Munich have all shown him to be way off the pace, and way off the form exhibited by Bellerín so far this season. As a result, he hasn’t even found himself on the bench in the last few games and a move away looks increasingly likely.
