Holiday cheer was hardly on display among England's managers this year.
Referee Mike Dean infuriated Manchester United manager Sir Alex Ferguson with his decision to award Newcastle United's second goal on Boxing Day. An own goal, it had previously been ruled out by the linesman's offside flag.
Ferguson showed his displeasure visibly along the touchline, on the pitch itself at halftime and yet more after the match. Such was Fergie's irritation that an onlooker might have been surprised to hear United won the game 4-3.
In the wake of Ferguson's hissy fit, Newcastle manager Alan Pardew suggested Ferguson should have been sent from the pitch. Ferguson responded by calling Pardew's Newcastle "a wee club in the north-east" (via The Guardian).
Never one to let Ferguson or Manchester United off easily, Arsenal manager Arsene Wenger waded in as well. The Frenchman agreed that Ferguson should have been punished (via The Independent), possibly in part because Wenger himself was once sent to the stands by Dean.
In an unrelated incident, Manchester City manager Roberto Mancini responded to Samir Nasri's controversial red card from Saturday by claiming referees have the easiest job in football (via ESPN FC).
All four managers face intense pressure and make an almost impossible job look easy at times. In this case, though, all four ought to be rapped on the knuckles. Acting like children deserves a child's punishment.
