Swansea 1-1 Man United: Ashley Williams on Van Persie incident

Swansea defender Ashley Williams says he did not deliberately kick the ball at Robin van Persie's head during their 1-1 draw with Manchester United.

Williams appeared to blast the ball at the United striker while he was on the ground at the Liberty Stadium.

United boss Sir Alex Ferguson says Van Persie is lucky to be alive and has called for Williams to be banned .
