Regarding Naismith, I think it's important to look for positives rather than negatives.
We 'need' a squad of players, and we're not in a position to have superstars in every seat in the stands, whilst taking a big slice of the wages.
It's important to have guys like Naismith.
He works hard, has great attitude, and is still only 26 years old. He cost us absolutely nothing to sign, and he must be doing something right, or Moyes wouldn't favour him. It's important to realise that when you come on as a late sub, you do so under instruction, and those instructions are there in order for the game to change in the way the manager hopes it will.
It's very possible that Naismiths natural game has to take a back seat to suit Moyes, and given that he is naturally a striker, he is often asked to do a very different job for the team. It's not easy to create impact at a late stage, but him coming on allows Moyes to release other players etc.
He has had a few good games this year, and his movement is actually very good, even if he has missed opportunities. His crosses have been poor, but he gets in good positions for goal, and a little luck can change things quickly.
Moyes is no mug, and he must have seen something in the guy, so we need to be a little more patient with him, and of course with Moyes' decisions. We're still with a shout if we can start scoring, and we need all the bodies we can get.
No doubt folk will moan about Barkley etc, but this is about Naismith, not anybody else.
