Another point I've seen raised re Fraser is that whilst he is not a dribbler he does have serious pace and work rate. As such he looks more like a potential replacement for Welbeck as a wide man, with the added bonus of being able to provide quality delivery.
IMO we lack pace in transition which is key with both MC & LFC to get the ball forward quickly and retain possession. Similarly I'm not sure dribbling ability from wide is key to the style we saw in the first half of last season where we looked to create an overload on one side before switching to the other.
