Mctominay is wasted at the back, even Clarke knows this.
Turnbull is as good in a defensive capacity as he is in attacking one, with a work ethic to match.
Gilmour, while possibly more suited to further forward, would still be a better option than Jack in that defensive role.
McGinn has played that role before and is a far superior player to Jack.
I understand it's your opinion, I just cannae believe that anyone would be of the opinion, that if you have 3 central midfield positions available, out of the talent we have, 1 MUST go to Ryan Jack.
