Manchester United officially announced Jose Mourinho's first signing on Wednesday.
The Red Devils have confirmed that Villarreal defender Eric Bailly has joined the club on a four-year deal, with an option to extend for a further two years.
"It is a dream come true to be joining Manchester United. To play football at the highest level is all I have ever wanted to do," Bailly told United's official website.
"I want to progress to be the best that I can be and I believe working with Jose Mourinho will help me develop in the right way and at the right club.
"I am looking forward to meeting my new teammates and to starting this new chapter of my life."
United did not release the transfer fee, but it is suggested to be about €40 million (R670 million).
The 22-year-old was part of the Ivory Coast team that won the 2015 Africa Cup of Nations, and made 47 appearances overall for Villarreal.
