Arsenal have denied midfielders Jack Wilshere and Mathieu Flamini were involved in a training ground altercation on Friday.
Wilshere appeared visibly irate with the Frenchman at Arsenal's Colney training base and had to be calmed down by right-back Bacary Sagna.

The photographs of the altercation were captured by the club's chief photographer, Stuart McFarlane, yet were still released through a photo agency.
Arsenal, however, insisted the pair were joking following a keep-ball session.
