(Reuters) - Arsenal captain Laurent Koscielny said he finally had a smile back on his face after making a successful comeback from a seven-month injury layoff in Thursday's 1-0 Europa League victory over Qarabag.

The French defender sustained an Achilles tendon injury against Spanish side Atletico Madrid in the semi-final of last season's competition and underwent surgery in May.
