It does indeed. However, look at the transformation of City once they got Navas. City had many small technical, quick enough but not fast, players like Silva and Nasri, but nobody to stretch the defense. Look at the space that a player like Valencia produces because of his pace - it's such a shame then that United have no players occupying the centre of the pitch in attack - they are either at the 18 yard box or ball watching somewhere else. A good winger doesn't need pace, but one of the two probably does. If we have Januzaj, although not slow, far from a young Giggs, and a Mata, quick but not over a distance, then teams know there is little chance of us running past them on the counter, thus allowing them to close us down high up the pitch. If we then also play Rooney and RVP, then out pace comes from our fullbacks, and that's about it. We'd be much too reliant on finding tight spaces in a crowded defense, as again we don't have the pace to stretch them.
