Arsenal defender Thomas Vermaelen has suffered an injury setback.
The Daily Mail says Vermaelen has suffered a delay in his return from a knee injury.
The Belgian was named on the bench for last Tuesday's draw at Southampton, but didn't make the match day squad for Sunday's win over Crystal Palace.
And according to Belgian sources, Vermaelen suffered a setback in training last week - picking up a slight calf strain - though the problem is not thought to be serious.
It is hoped Vermaelen will be available again within two weeks
