Leeds United have signed Real Sociedad defender Diego Llorente on a four-year deal for an undisclosed fee, understood to be around £18m.
The Spain international will provide competition for current centre-back pairing Robin Koch and Liam Cooper.
Former Real Madrid player Llorente, 27, can also play in midfield.
He is the newly-promoted side’s fourth major signing of the summer following their Championship title win last season.
Leeds have spent significant money, including a club record £26m for Valencia forward Rodrigo, £13m on Freiburg defender Koch, and £16m on ex-Wolves winger Helder Costa.
“It was a difficult decision for me and my family [to leave Sociedad] but I have taken the best decision of my football career,” Llorente told BBC Radio Leeds.
“The coach [Marcelo Bielsa] has been an important factor. I can improve under him and it will be an honour to learn from him.
“I spoke with Pablo [Hernandez] a few days ago. He told me about the city and the team, and I have also played with Rodrigo in the national team.”
Llorente, who will wear the number 14 shirt, has won five international caps for Spain.
