They are equally not good enough to progress our team but of the two Luiz still has the potential. I don’t think there’s much left to see from McGinn in terms of development.
he runs about a lot but he hasn't been a great link between attack and defence. Not good enough to take the ball and turn and gives the ball away quite a bit. I’d rather see Luiz given a chance at no8 than another season of SJM.
That said we should retain him as a squad player
