Arsenal were heavily criticised last season for their performances at the back.

Shkodran Mustafi took the brunt of the criticism, while Laurent Koscielny also came under fire.

The season ended terribly for the latter, though, as he suffered an Achilles injury that ruled him out of France's World Cup campaign in Russia.

The centre-back, who has been capped 51 times for his country, is now working towards full fitness.

At the age of 32, though, it is fair to suggest that Koscielny could struggle to earn his way back into the setup.

On Monday, the defender posted a video on Instagram showing that he is now able to walk without the use of crutches.

Arsenal have not provided a definitive timeline of recovery for the Frenchman, but plenty of fans are keen for him to make a comeback.

As well as ousting whoever takes one of the centre-back slots, Koscielny will have to impress new manager Unai Emery, who has added to the defence this summer by recruiting right-back Stephan Lichtsteiner.

On Reddit, Arsenal fans have been posting their reactions to the defender's injury update.
