Nottingham Forest manager Aitor Karanka hailed the development of Ghanaian youngster Arvin Appiah.
Appiah has been hailed as one of the best players in his age rank following his impressive display for the Three Lions during the European U-17 Championship.
Karanka said: “Arvin is only 17 or 18 and he already looks like a man.
“He trains really well with us. Every single player is different and we will manage them in the best way we can.”
The 17-year-old, who is born in Holland, is eligible to play for Ghana through his parents.
