Because Yiadom might need a rest..
Because Gunter is .surplus to requirements and not match fit.
Because Rhino at RWB might be better than either Howe or Watson
and it allows for Rhino to go central if Adam or Pele are pulled
You have 4 RBs at your disposal. Two young products of your academy who went on tour with the first team. And you choose to play your best midfielder out of position, into a position where his performances have been mixed.
Might as well tell Howe and Watson to pack their bags.
Were either of them involved in the U-23 game on Monday? If so, that might be why they weren't involved.
Believe Gunter played. Surely the first team takes priority
