My preference would have been to have a go at them with our strongest team. In saying that the decision to leave the 3 behind doesn't really bother me. Especially since I am not sure what our strongest team is!
I assume McCall knows what his tactics will be and I would have been inclined to leave Sutton out and go with someone more mobile up front anyway. I think similarly in midfield he will be going for more energy and workrate in place of the chance of Faddy producing a brilliant moment.
I don't think he lacks ambition, just that he is realistic and as someone mentioned, may well have chosen not to start the 3 of them anyway even if they had been there.
Still holding out hope for a 3 - 1 win for super well
