I think Nelson's gonna be fine too in the short term. The main problem will be that we won't play him this season, despite the team crying out for someone with his skillset.
Next season, when he's deemed to have caught up physically and gets the chance, it'll often be out of position and we'll quickly become overreliant on him to the point where he plays way too many games in quick succession. Que a few years of bad hips, knees, ankles, etc.
Edit: Then again, that's not what happened to Iwobi so maybe I'm being unfair. Perhaps we've learned some lessons from the last decade.
