Taking on Roy Keane is no mean feat and former Chelsea captain John Terry decided better of it after twice deleting a tweet criticising the ex-Manchester United hard-man.
Keane was left far from pleased on Sunday after he was pestered by a fan for a selfie while watching an NFL match at the Tottenham Hotspur Stadium between the Green Bay Packers and the New York Giants.
The clip went viral, leading to Terry to have a pop at his old adversary... only to bottle it minutes later.
This NFL fan asking Keane for a selfie must have been American.
