It could have more to do with playing fixtures close together with a small squad than any physiological aspect. Squad rotation only works if you have players of almost equal strength.We have to get Graham back on the right .Ogilvie in at centre back. O'Connor at left back.Maybe play a traditional 442 formation allowing Samuel to play alongside Oliver not behind him to the right.That does leave a gap on the left hand side which needs addressing unfortunately. But better that than what we have even if it means we become a bit one sided .Better that than no sided.
