I think Naismith (and McCarthy) are probably our two most consistent performers. We have other players who may have outstanding games one week but then are off the boil the next week. Naismith has not only scored goals but his link up play is good. Even last week, where we didn't play well as a team, I thought he did well until he got a bad knock and he later laid on a great ball for Delboy which was incorrectly called as of-side.
I think that the big Q is about Lukaku. He has some very strong parts of his game and some weak ones too. He is young and probably will develop but can we wait? Can we afford him? Tough call.
