Sheffield Wednesday have completed the signing of defender Tom Lees from Leeds United for an undisclosed fee.
The 23-year-old made over 130 appearances for the Whites since graduating from the club's academy but now moves to their Yorkshire rivals on a three-year deal.
"We've been in talks and I've been hoping everything was okay and I'm delighted to have put pen to paper," he told the Owls' official website.
"You never know with any deal until it's signed, of course, and I couldn't be happier.
"This is a massive football club steeped in top-flight history for most of its existence and I can't wait to get started.
"I've spoken to plenty of players who have played for Sheffield Wednesday and they can't speak highly enough of the place.
"Obviously, that has a big bearing on your decision and it's great that so many people in the game speak so well of this club."
