Again, that's just mere speculation and not very flattering for our Mnagaer either. After all, he was successful here before and obviously enjoyed the experience so, for all we know, he might be as happy as a sandboy at Tulloch and itching to get a win or two to start the big ball rolling.
Secondly, the question of whether or not by going to Hearts he has, or has not, got any integrity is clearly not an acceptable assessment of his character at all. Since we all have yearnings at some point in our lives that conflict us then it has to be only what's written into his contract that counts for both himself and the club. Because, if his contract terms are such that he can go for a certain price, IF the offer is put in writing to the club and the club accepts it, then that allows him to act in his own interests first and then the club has to have their own integrity of purpose by actually signing the new transfer deal's contract to finish the matter.
As far as I know John Robertson has not shown any lack of integrity that can allow such speculation so why don't we just wait and see.
Maybe Hearts think that he has been out of a managerial position for too long anyway and appointing him would not be the best option for them.
Best to see all, hear all, say nowt and keep yer powder dry,Corporal, on this integrity stuff.
