Jahmal Hector-Ingram completed his move to Pride Park in August, following an impressive spell as a trialist during pre-season.
The striker scored five goals in six games to earn a permanent contract with the club following his release from West Ham United at the end of the 2018/19 season.
Hector-Ingram spent 14 years with his boyhood club and he caught the eye by recording a goal and assist against Derby for West Ham back in April 2019 in a 2-2 draw at Pride Park.
After his signing was confirmed, Academy Director Darren Wassall said: “When a trialist comes in, especially a centre-forward, all you can ask is that they score goals. He has done that and shown he is a great finisher.”
