Unpopular opinion incoming....
I would call time on Grant Hanley.
His pride, his commitment and his effort I cannot fault but nonetheless he's a major liability in my opinion. The frequent lapses in concentration, bad decision making, clumsiness and poor positioning are screwing us. Also, in contrast to the other players he always looks absolutely wrecked (beetroot red face, dripping with sweat, panting for breath) after about sixty five minutes/seventy minutes are on the clock. Is it that bad fitness or a sign of health problem ?
Only call up players like Gauld and Morgan if they are actually going to get serious game time. It's a complete waste of their time to fly them all that way over just to sit on the bench or bring them on in the 89th minute to waste time.
I doubt they will be called up in any case.
