Arsenal boss Arsene Wenger is fed-up with dressing room leaks.

Wenger has hinted a search has been launched to uncover the mole.

The latest behind-closed-doors escapade to reach the public domain was the incident last week after the defeat against Southampton when goalkeeper Wojciech Szczesny was caught smoking in the showers - a transgression against club rules that earned him a £20,000 fine.

"I don't want to talk about that because what happens in our dressing room stays in our dressing room - apart from the fact it does not stay there," he said.
