Laurent Koscielny: Leaves with dead leg

Koscielny was replaced by Calum Chambers at halftime of Sunday's match against Leicester City because of dead leg, according to Phil McNulty of the BBC.

Analysis:

Chambers has found regular playing time a bit hard to come by this season, and it's a bit interesting that he got the call ahead of Gabriel Paulista, who had been starting in place of Per Mertesacker of late.
