Noah Sadiki

Sadiki can play as a full back, a centre back or a defensive midfielder without any of those positions looking unfamiliar to him, which made him valuable to a Belgian side that won major honours during his time there. His engine stands out most, since he covers as much distance as any player in Sunderland's squad and rarely looks fatigued deep into matches. That stamina lets him press high and still recover into a defensive position moments later.

The trade-off with a player this versatile so young is that he has not yet settled into one specialist role, and Sunderland still seem to be working out where he fits best long term. He compensates for that uncertainty with effort and reliability rather than a single standout attribute. Watch which position he ends up occupying most often, because that will tell you where his future lies.
