Manchester United manager Sir Alex Ferguson has called on the FA to ban Swansea's Ashley Williams for kicking the ball at Robin van Persie's head.
The centre-half's clearance hit a prone van Persie at point-blank range during United's 1-1 draw in south Wales, prompting an angry response from the Dutchman.
Williams - booked at the time - afterwards insisted it was a complete accident, but a simmering Ferguson claimed Van Persie could have been killed and called the act "absolutely deliberate".
