Didn't see the game against Killie yesterday so can't comment, but in the first leg he did everything that I would expect of a no.1.
In terms of signings that probably should have been a signal of intent, Seve would probably fill that in recent memory. Arguably the biggest name player to sign for us for a while.
Of the list you've named, i'd be overjoyed if we got any of them, but I can't see it happening, certainly not when we're being linked with the likes of Greer...
