Arsene Wenger has confirmed he will meet Jack Wilshere to reprimand him after a picture emerged of the young midfielder smoking.
The picture, which appeared in national newspapers this morning, showed the Arsenal youngster smoking outside a London nightclub after the Gunners' 2-0 win over Napoli on Tuesday.
Wenger, who famously provoked outrage amongst the Arsenal players in 2006 for banning alcohol, smoking and chocolate, says he will meet Wilshere over the incident.
The Arsenal manager said in his press conference: "Well, I disagree completely with that behaviour.
"I need to have a chat with him about that. (What I say) I will leave between him and me.
"When you're a football player you're an example, and you don't do what damages your health."
Not only was Wenger noticeably angry with the player for smoking in the first place, but has also criticised Wilshere for doing so in a public place.
Wenger insisted that Wilshere has not only damaged his health but his reputation as a professional athlete as well.
"You can damage your health at home - you can smoke or drink at home - and nobody sees it, but when you're out socially, you damage your reputation as well."
Wilshere, 21, has made a slow start to the season and has seen himself fall behind Mathieu Flamini and Aaron Ramsey in the centre of Arsenal's midfield.
However, despite his mixed form and indiscretions, Wenger revealed that Wilshere remains part of his long term plan for the club.
"Wilshere is a very important player here, my future plans have always been built around Jack," the Frenchman added.
