Arsenal manager Arsene Wenger has assured youngster Ainsley Maitland-Niles he has his full support.

Police were called to the Premier League club's Hertfordshire training complex in March following a confrontation between Jule Niles, Arsenal executive Dick Law and her son's agent, and again last month when she had subsequently threatened to withdraw the winger from an under-21 match before refusing to leave the premises.

No charges followed, but Niles has been issued with a warning.

"It is basically a private matter that I don't know really well about because I don't know what happened, but I know Ainsley very well and he has my complete support because he is a good boy and I am sure his mother wants a great future for him and to help him," said Wenger.

"There are some incidents that I don't know well and I don't know why, but the boy has a perfect behaviour inside our club. There are many times in the week with me in training."
