Newcastle United coaching staff clashed with Manchester United players during yesterday's seven goal thriller.

Toon boss Alan Pardew was furious with United winger Antonio Valencia over an injury-time tackle which saw Vurnon Anita carried off with an ankle injury.

His assistant John Carver had an angry exchange with Rio Ferdinand at the end as tempers threatened to boil over.

Pardew said: "I was upset about that tackle and it got lost a little bit. I don't think it was malicious or that he was trying to hurt him - but he mistimed it and it may cost us a player.

"Vurnon's got a bang on the ankle and might not make Arsenal and that would be a shame because he has been terrific."
