CB) Laurent Koscielny
It’s been a frustrating season for both Arsenal and Koscielny. His bouts on the sidelines have corresponded with his side’s periods of poor form showing just what a vital cog in the machine he is.
Hopefully if he returns as expected against West Ham it will be on a more permanent basis.
CB) Per Mertesacker
If Koscielny is back, you’d expect that to do wonders for he game of the big German who like the team has struggled without the Frenchman.
