#5 Keano’s Wrath (2001)
It was yet another infamous Manchester derby in April 2001. Roy Keane, probably the most intimidating midfielder of his time, got himself sent off for aiming a knee-high kick at Alf-Inge Håland in the 85th minute.
Supporters were horrified as many believed he had committed the foul as an act of revenge. Three years prior to this incident, when Håland was a Leeds player, he had taken Keane down causing a ligament injury and gone on to insinuate that the United man had faked his pain.
A year after the derby incident, when Keane released his autobiography, the repercussions of that night were to continue. He confirmed his premeditated intent to bring down Håland because of what he had done to Keane.
The FA reacted strongly imposing additional bans and fines to the ones from the year before.
