When you consider our lack of HG players and the fact we likely won't renew Werners loan, have got rid of Perisic and will likely sell Gil and Solomon, depth is exactly what we need for the wide positions.
What he can't be (if we do sign him) is the star winger in the team. Whilst I think if he fulfils his potential, he could be, we need someone who can come in now and like you say, surpass Son.
Hudson Odoi would be a smart signing, HG, brilliant technique, brilliant dribbler and can play either wing. But hes depth and opportunistic based on Forests financial troubles.
Still the best youngster I've ever seen at youth level though in this country so I am probably bias towards him anyway
