Could Mathieu Debuchy save his Arsenal career?

Mathieu Debuchy’s time at Arsenal has been underwhelming to say the least.
The France international joined from Newcastle United as a proven performer in the Premier League and for his country – making him a perfect fit.
But after some initial promise, he struggled with injuries and was soon usurped by Hector Bellerin’s emergence from the youth team.
Debuchy had a loan spell and Bordeaux to try and bounce back, but it didn’t work and he’s since been stuck in the Under-23 team.
A transfer has proven tricky, despite betting companies like NetBet Sport expecting it to happen, and this year he’s been playing centre back for the second string as they mirror the first-teams back three.
However, while many would expect dropping down to play with kids and moving to an unfamiliar position would see Debuchy decline further – he’s actually impressed and looks really good in the position.
Part of Debuchy’s problem has been the pace he’s lost, but at centre back it is less of an issue and the switch appears to have revitalised him.
It’s a stretch to imagine there could be a way back for him at Arsenal, but with Mustafi, Koscienly and Chambers all currently injured, and with little other option, a return to the fold would make sense.
Debuchy looks likely to reject moves and continue to pick up his reported £70,000-a-week salary until the end of the season, so in which case Arsenal might as well try and get some use out of him.
