Manchester United manager Sir Alex Ferguson and assistant manager Carlos Queiroz have both denied charges of improper conduct.

They were charged in relation to media comments made following Manchester United's FA Cup Sixth Round tie against Portsmouth in March.

Ferguson's charge concerns comments about referee Martin Atkinson and PGMO General Manager Keith Hackett.

Queiroz's charge relates to comments about referee Martin Atkinson.

Both parties have requested personal hearings which will be scheduled in due course.
