Forces: The greatest strength of Nkounkou is undoubtedly his versatility, the 19-year-old is able to play in the left back or in the midfield on the wing.
Given this versatility, another impressive asset is its speed and its ability to beat the opposition’s defenses from a standing start.
Nkounkou’s style of play is probably a modern back, playing effectively as a defensive end.
Definitely a player who will be delighted to see Goodison in the near future.
