I said on fb and twitter yesterday that Chambers was arguably better than Shaw. When you think about their progress and the fact that Shaw has had most of the plaudits, Chambers has actually done very well. He's better going forward, has more skill, a better touch and defends well too. I think he's been bloody excellent and does, I guess, give the option of playing him further forward. Shaw has been inconsistent lately and does seem to pick up injuries. I know he's young, but so too is Chambers.
They're both great young players of course, but at the moment, I'd say Chambers is playing better.
