I always think that when Navas comes on, or starts, the play will be, if nothing else, 'direct'! There's plenty of talk about 'glass ceilings', but Navas seems to hit a glass wall when he gets down in the corner. He would be some player if he could ever dribble past his full back, get to the goal line and pull it back, or even cut inside and shoot! These are things that I have seen Roberts do regularly. There were two Celtic fans in front of me on Tuesday. (I don't know what we'd done but they didn't reappear for the second half!) They were very enthusiastic about him. Directness with an end product! It is Messi-like!
