Derby have completed the signing of Manchester United midfielder David Jones in a £1m-plus deal.
Jones has had a successful loan spell at Pride Park
The 22-year-old, who had been on loan at Pride Park since November, has agreed a three-and-a-half-year deal with the Championship club.
Jones made four appearances for the Old Trafford club and has played for England Under-21s.
Derby boss Billy Davies said: "I'm delighted to have secured the services of such a talented young player."
Davies added: "I'm sure from what he's shown for the Rams so far that the Derby fans will know we've signed a first-class footballer.
"David has settled in really well at the club and shown signs of his quality.
"I'm sure he will get better and better the more games he plays."
