Throughout the 2000s, Keane maintained a healthy rivalry with Arsenal captain Patrick Vieira. The most notable incident between the two took place at Highbury in 2005 at the height of an extreme period of bad blood between United and Arsenal. Vieira was seen confronting United defender Gary Neville in the tunnel before the game over his fouling of José Antonio Reyes in the previous encounter between the two sides, prompting Keane to verbally confront the Arsenal captain. The incident was broadcast live on Sky Sports, with Keane clearly heard telling match referee Graham Poll to "Tell him [Vieira] to shut his ****ing mouth!" After the game, which United won 4–2, Keane controversially criticised Vieira's decision to play internationally for France instead of his birthplace of Senegal. However, Vieira later suggested that having walked out on his National team in the World Cup finals Keane was not in a good position to comment on such matters.Referee Poll later revealed that he should have sent off both players before the match had begun, though was under pressure not to do so.
