Nabi is 18 at the moment, 19 in February or March now. He was great at schoolboy level and started well at academy level but faded. He hasn't developed much physically and here might be question marks over his pace and power at the pro level but he seems to be scoring again now he has gone from under 18's to under 21's level.
When I have seen him, he has bee very lively and confident. He seems to play just behind the strikers and likes to go for goal.
