petrov is slow and i just don't rate him much ..... huddlestone can pass but he is slow, can't tackle (or move for that matter), his positional sense is non-existent and his work rate is abysmal, oh and his passing is wayward - nothing like he is made out to be simply because he plays for a london team ..... like you said etuhu is limited - good at what he does, yes but no improvement on lucas and he is getting on so has very little scope for improvement unlike lucas
