RE: 777 Landing Observation

If there is a strong gusting crosswind, wouldn't it be very difficult to coordinate the rudder with the ailerons to point the nose down the centreline and at the same time ensuring the wings to be level? I would think this method would only be pretty much easier when the crosswind is rather stable o...
