Nothing to do with the point I was making, which is providing width doesn't mean player shouldn't cut in.
Also not sure how you came up with Winger is supposed to cut in and FB should be hugging line.
Because this is what supposed to happen. The winger and fullback shouldn't be occupying or getting into each other space, it gets crowded, easy to defend against and leaves the flank open without any support. If the winger cuts in on his stronger foot, the fullback should overlap him in the open space to create chances for crosses. Basic football.
