Derby County have signed midfielder Jacob Butterfield from Huddersfield Town.
Butterfield has joined Derby, who pursued him throughout the summer window, for an undisclosed fee.
However the Examiner understands the deal is around £5m.
The former Middlesbrough man has agreed a four-year contract at the iPro Stadium and will wear the 18 shirt.
Butterfield had been an integral part of the Town team ever since he moved from Middlesbrough a year ago for a fee Town have confirmed as £500,000.
Town now face the challenge of finding a replacement for a player who himself came in as Adam Clayton departed to Boro and fellow midfielder Oliver Norwood to Reading.
Derby head coach Paul Clement said: “ I’m delighted that we’ve been able to bring Jacob Butterfield to Derby County.
“As I’ve stated publically in the last few weeks, if we were going to add to our squad it would be a case of making a quality addition rather than bringing someone in just to make up the numbers.
“In Jacob, we have a very talented player and an individual that is experienced at Championship level.
“He is positive addition to our already strong squad and in light of Will Hughes injury, Sam Rush and Chairman Mel Morris have worked tirelessly to get this deal over the line.”
