Arsenal's Laurent Koscielny: Back with Arsenal

Koscielny returned to training on Wednesday after his extended holiday following the European Championship.

Analysis:

Koscielny's work toward fitness is of utmost importance for the Gunners, who will be without Per Mertesacker (knee) for a number of months and Gabriel (ankle) for up to six weeks. The season doesn't start easily either, as Arsenal will host Liverpool before traveling to face Leicester City on 20 Aug.
