Arsenal defender Laurent Koscielny showed great temperament to deal with Diego Costa during the Gunners’ loss to Chelsea in September, but things might well have played out differently. The French defender appeared to be slapped by Costa in the match and admitted that friends have since told him they had no idea how he kept his cool. To quote, Koscielny was told he should have hit the Spain international. Since Arsenal ended that game with nine men anyway, it’s probably a good thing that he refrained. In other news, Alex Oxlade-Chamberlain has looked to update fans on his injury issues, posting a picture to Instagram confirming that his rehab is going well. The midfielder said he was looking forward to being back on the pitch soon - the international break should give him more time to recover.
