The square peg, round hole thing is thrown at Robinson as if it's something unique to him.
Look at Sean Clare, last season at Charlton he played CB, CM, DCM, RW and RB. With us he played at RB, CM, DCM and RW. The season before that at Hearts he played RB, CM, RW, ACM, LW and CF. The season before that at RW, CF, ACM, LW, CM.
So at least three different managers at three different clubs have played Sean Clare in multiple positions, and he's not set the world alight in any of them. So maybe the problem sits with the player rather than the manager?
