Arsenal boss Arsene Wenger is unhappy with Jack Wilshere's smoking.
Wilshere was snapped puffing away yesterday.
"I disagree completely with that behaviour," said the Frenchman, whose side face West Bromwich Albion.
"First of all, when you are a footballer you are an example, and second, you don't do what damages your health.
"You can damage your health at home. You can drink at home but nobody sees it, but when you do it in public, you damage your reputation as well.
"What will I say to him? I will leave that between him and me."
