Arsenal manager Arsene Wenger says he will speak to Jack Wilshere after the midfielder was pictured smoking in a national newspaper.
Wilshere was pictured holding a cigarette whilst on a night out with friends.
But Wenger says his future plans for the team are still built around the England international.
However he said that he finds Wilshere's behaviour unacceptable.
"I disagree completely with that behaviour," Wenger said in today's press conference.
"I don't know what has happened and I will have to have a chat with him about that. When you are a footballer you are an example and also don't do what damages your health.
A spokesman for Jack Wilshere has subsequently insisted that the Arsenal midfielder does not smoke despite the evidence from the photo...

On the other side of North London, fellow England international Kyle Walker was forced to apologise after he was photographed inhaling Nitrous Oxide - a potentially lethal substance.
But the Tottenham full back faced no disciplinary charges for taking the legal high.
Wayne Rooney and Ashley Cole have been photographed smoking in the past.
