An extract from our procedures:

AUTOLAND
The Autopilot flies the aircraft onto the runway with a rate of
descent of approx. 150 ft per minute and without removing any
drift. This is a safe manoeuvre up to the autoland crosswind
limitation. The Autopilot must be disengaged at or shortly after
touchdown. If the autopilot is left engaged it will lower the nose
gently but if there is any crosswind there is a tendency for the
upwind wing to lift.

Rudder must not be applied prior to touchdown as the autopilot will apply aileron to counteract this input and the aircraft may drift off centreline. In addition, manual rudder inputs may lead to roll
oscillations and increased touchdown dispersions. Any drift that
was present on touchdown should be removed gently by rudder
after both main wheels are on the ground. Reverse thrust and
brakes/autobrakes should be used as in the manual landing case
