FC Groningen defender Mike te Wierik has signed a pre-contract agreement to join Derby County in the summer.
The 27-year-old captain of the Dutch Eredivisie side will move to Pride Park on a three-year deal.
Te Wierik is the first Dutch signing made by former Netherlands international Phillip Cocu since taking over as boss of the Championship side.
"He is a good defender and a leader," Cocu said. "I have no doubt whatsoever he will fit into our style of play."
Te Wierik, a former Dutch Under-21 international, has made 85 top-flight appearances for Groningen since joining from Heracles in July 2017.
While Derby have at times struggled under Cocu, with off-field problems plaguing their campaign, they are mid-table after a surge in form following the arrival of former England captain Wayne Rooney as a player in January.
Derby won three and lost just one of five league games last month, a run that has seen former Eredivisie-winning PSV Eindhoven boss Cocu nominated for the Championship manager of the month award.
