Alan Pardew has warned Sir Alex Ferguson there will be two angry managers in the dug-outs when Newcastle head for Manchester United on Boxing Day.

The Scot was apoplectic after Sunday's 1-1 Barclays Premier League draw at Swansea which saw the leaders drop two precious points, but also striker Robin van Persie react furiously after being struck in the back of the head by the ball when defender Ashley Williams blasted it into him as he lay on the ground.

Ferguson later voiced the opinion that the Dutchman could have been killed in the incident and called for retrospective action to be taken, and he was not placated by Williams' insistence that it had been accidental.
