According to reports in The Telegraph today, Arsenal have given Ainsley Maitland-Niles' Mum a ban from the training ground after she allegedly hit a club negotiator.
The incident took place last month after an argument between the player's mother, Julie Niles, and Arsenal top brass Dick Law. It's not the only row she's been involved in either: a member of the ground staff has also accused her of assault which lead to her arrest. Niles was later released without charge.
At only 17, Niles has made it into the Arsenal first team and played at Champions League level (possibly based on the fact Wenger is sh** scared to drop him in case his Mum gives him a right hander).
