Manchester United have signed versatile Netherlands international Daley Blind from Ajax for £13.8m.
Blind, 24, who agreed a four year deal, was in United coach Louis van Gaal's World Cup squad and can play at left-back and as a defensive midfielder.
The latest transfer brings the Old Trafford club's summer spending total to over £143m on five permanent deals.
"I cannot wait to work with Van Gaal at the biggest club in the world," Blind told the club website.
"It is a real honour to sign for Manchester United. I have been at Ajax since I was seven years old and I will always have very fond memories of the club and of my time there."

Blind, the son of ex-Netherlands international Danny, worked his way up through the youth system at the Dutch club giants and helped them win four league titles.
He has won 19 caps and scored his first goal for his country in a 3-0 victory against hosts Brazil in the World Cup third-place play-off in the summer.

Last week, United broke the British transfer fee record by spending £59.7m to bring midfielder Angel Di Maria from Real Madrid.
In addition to the permanent signings, United have agreed a £6m one-year loan deal with Monaco for Colombia striker Radamel Falcao.
