I genereally think both Nelson and Willock are better than Iwobi, they have higher energy levels, better teqnique, more stamina, better defensive awareness, score more goals, can dribble better. The only thing that iwobi has over them is physique.
The difference is that Nelson and Willock are doing those things in u23 league while Iwobi is doing well in Premier league.
Iwobi was very good at u23 level.
