Well Russell Martin is more likely to be permanent than Naismith isn't it, because the latter probably on about 250% more money.
That said, Naismith would instantly go up in my estimations (and the estimations of Rangers fans after he walked on a freebie) if he did actually take a substantial pay cut in order to play regular football.
He is apparently really good friends with Graham Dorrans also (has been for many years before joining us). Presumably joining up with Dorrans, plus Martin and Whittaker was a big part of the reason he came here in the first place.
I see that Rangers haven't learn their lesson though, were on the right track with Warburton signing talented youngers from England who he could turn into good players to last 5 or even 10 years, now they've reverted back to paying big money to 30 year olds. Might give them a short term buzz to sign Naismith back, but not going to help them catch Celtic is it?
