I quite like Callaghan in the squad as cover for Davidson who historically misses games each season through injury and suspension.He is not,and probably never will be a playmaker but has a tremendous workrate..TW said earlier this year that his priority was signing a playmaker and now he appears to have settled on the two young guys to fill that roll .Only time will tell if he is right but it is another area where we need more creativity..My personal wish list would be another central defender who can cover a full back position,a creative central midfield player and two forwards with McMillan +1 (probably Swanson) departing.....I know it's not going to happen though
