Academy graduate Jason Knight had a whirlwind end to the 2018/19 campaign.
The midfielder was named as a substitute in the memorable 4-2 victory over Leeds United at Elland Road which secured the Rams a trip to Wembley for the Play-Off Final, and he was also named on the bench for that game against Aston Villa in May.
Although he did not feature, the youngster has made significant strides in his development.
He appeared for the Republic of Ireland Under-21s at the Toulon Tournament this summer as they reached the Semi-Final stage before being beaten by Brazil.
Knight has featured prominently under new manager Phillip Cocu in pre-season and made his professional debut as a substitute on the opening day of the 2019/20 season as Derby ran out 2-1 winners at Huddersfield Town.
He went on to make his first-ever career start in the 1-0 Carabao Cup First Round victory at Scunthorpe United just over a week later.
