If you want to think about fullbacks, remember that this is juventus, not brazil, and the coach is antonio conte, not zeman.
Wingbacks are rated on their total package, with a high importance to defensive capabilities, and domminating the wings. Conte will not remove a wingback,for another, that is considerably worse at defending but can cross.
Because of this, i cant see peluso/asamoah and licht be replaced in the near future. Isla remains to be seen, but licht wont move for anyone thats not on par defensively. and very very few are in europe. Nobody in italy beats asamoah or licht on their wings.
