When Mathieu Debuchy suffered a dislocated shoulder in January the feeling it inspired in Arsenal fans was as frustrating as it was familiar.

The Frenchman had only recently returned from a three-month spell on the sidelines before Stoke City's Marko Arnautovic shoved him into the advertising hoardings at the Emirates Stadium with predictable results.

It was a blow that seemed especially cruel for a club that had to travel north to face the Premier League champions the following week with two largely untested 19-year-olds to deputise.

But both Calum Chambers and Hector Bellerin have shown glimpses of real form and talent in his absence.

Debuchy has now returned from injury, but whether Arsene Wenger should reinstate the former Newcastle defender is open to debate.

The most experienced of the three, Debuchy started the season as clear first choice. An established international, who has proven himself in France and England, Debuchy is the obvious option.

He's the strongest in air and is widely considered the most reliable. But he's also only played 10 league games this season, and hasn't featured at all since the turn of the year. Bringing him back into the side now could disrupt a defence that has only conceded three goals in the last five games, and has only lost two matches in his absence.

Arsenal have won nine of the 10 fixtures Bellerin has played in since Debuchy's injury and the former Barcelona youth team player is on the verge of being rewarded with a new contract.

Bellerin is weak in the air but makes more interceptions per game than his competitors, is the most effective going forward and Arsenal have won a staggering 75 per cent of their league matches when he has played this season.

The hype around Chambers was so great at the beginning of the season he'd earned three caps for England by mid October.

Chambers has played almost as many league games as the other two combined this season, although his form dipped towards the end of 2014.

While he may not boast the defensive solidity of Debuchy or the attacking prowess of Bellerin, Chambers offers a balance of the two, with no real weakness other than a slight susceptibility to pace.
