Derby midfielder Will Hughes has signed a new four-year contract.
The highly-rated teenager, who has regularly been watched by scouts from Barclays Premier League clubs during the past two seasons, had two years remaining on his existing deal but has now put pen to paper until 2018.
He becomes the fourth player to commit his future to the club following fellow midfielders Jeff Hendrick and Craig Forsyth and central defender Jake Buxton.
Derby head coach Steve McClaren said: "We're pleased that Will has decided to extend his contract with Derby County for the next four years.
"He is a promising young talent and we're looking forward to working with him over the next few years to help continue his development."
England Under-21 international Hughes, who came through the youth ranks at Derby, made 48 first-team appearances last season for the Rams, scoring five goals. The 19-year-old was also named in the PFA Championship team of the season this year.
