Arsene Wenger was involved in a tunnel bust-up with counterpart Ronald Koeman following Arsenal's 0-0 draw against Southampton on Tuesday night.
Arsenal endured a frustrating goalless stalemate against the Saints and the result leaves them five points behind leaders Leicester City in the Premier League table.
Wenger was not happy with referee Lee Mason's performance during the clash and had waited for him in the tunnel to remonstrate. Wenger then reportedly shouted at Mason: "It's always the same with you."
Southampton manager, Ronald Koeman, saw the exchange and took exception to Wenger's behavior. In retaliation, the Dutchman told Wenger: "It's always the same with you. You had 10 chances to score and didn't take any of them, instead you take it out on them (the officials)."
