Essentially no striker will be on the face of it unless we do somehow get Kane back who as you’ve said can fashion said chances for himself as well as others but that ain’t happening.Lewandowski isn't the right player to bring in until we are in possession of wingers who can stretch the pitch and midfielders who can pass further than 5 yards without losing possession.
He is deadly in the box if others create chances for him, and even in his absolute prime he wasn't amazing at creating chances for himself (which is why I rate Kane as the better all-round player of the two, even if Lewa has been more prolific and much more successful).
We ain't solving all our problems in one window, so a certain amount of triage is needed. First things first is to sort out LW (hopefully not Savinho or Summerville), after that is the absolute nonsense going on in CM, after that is dealing with gaps left by players leaving. And that my friend is more than enough for one window, especially for a club as dumb as us.
Lewandowski would represent an upgrade on dumb and dumber though and have a higher chance of finishing the few chances we do create. Richarlison probably finishes roughly one in four, Solanke about one in five. The top strikers do it inside three, even two.
