That is such a ridiculous inclusion. Bad enough Rashford and Walker in there, but Henderson is just bizarre and a backwards step. It’s put all the wrong attention on the squad and is a negative start for the manager.
The only thing I can think of is that he has no interest in playing him but just wants someone with experience in the squad to help Tuchel. But he could just ask him to join up with the squad and not be in the squad.
