 The ill feeling was originally sparked by an incident between Van Nistelrooy and Patrick Vieira.Having been fouled by Van Nistelrooy, Vieira aimed a kick in retaliation; although the kick did not make contact, he was still sent off for a second bookable offence.Van Nistelrooy was accused by both Vieira and Wenger of feigning contact to get his opponent sent off, while Ferguson defended his player and denied he had dived.
