The tensions between Sir Alex Ferguson and Roberto Mancini came to a boil on Monday night when the two managers squared up against each other along the touchline.

The incident that sparked the war of words was after Danny Welbeck got fouled while making a run down the wing. As you can see from the video, both Mancini and Ferguson had plenty of words for each other as well as hand gestures telling each other they talk too much. Luckily, the fourth official and coaches were able to break up the skirmish before it resulted it anything.
