Rooney actually played well in that role last night, and he's certainly better suited there supporting someone like Kane - or, indeed, Vardy or Rashford - than he is anywhere else. Some may remember the short-lived experiment/disaster of playing him on the left wing at the last world cup.
Sterling deserves to be singled out more than Lallana. A good idea might have been to take off Sterling and put Vardy on.
I could have understood putting the lone striker on corner duty if he was any good at them, but several of them were way too high and long.
