It's a bit naive to suggest that the striker we put up top wouldn't change the way we build up in the final third. If we had a massive bustard like Lukaku up there you can guarantee we'd be putting in far more crosses, if Kane was still here you would see interchange between him and Maddison.
Ive not completely written off Richy but his lack of involvement in shots is as much if not more down to him having an average to poor touch, not great in the air and not an especially gifted dribbler or very quick. If we were to set up just to feed him in the box we would get far less team goals, we need either Richy contributing more with 3rd man runs and offering a meaningful presence in the box, or replace him with someone who can offer that.
