This is not the best we can expect from him. I think the minimum is he gives us most of what Bernard gives us but with slightly less pressing. Although he adds the ability to dribble from deep into the attacking third and to pass the ball into the box.
The best is he does all that but adds more consistency to his creative play in the final third and maybe scores a few more. I'm not sure where this myth that Iwobi is one of those players that does a bunch of tricks and not much else has come from but it is actually a myth. He does do some tricks, It is not all he does.
