Manchester United has signed Tyrell Malacia from Feyenoord on a four-year contract with the option of a further year.
The fee is an initial €15 million (£12.9 million) with up to another €2 million to follow in add-ons.
Malacia is a 22-year-old left back.
“It’s an incredible feeling to have joined Manchester United,” Malacia said. “This is a new chapter for me, a new league with new teammates and a tremendous manager leading us. I know from playing against his teams in the Eredivisie the qualities that he has and what he demands of his players.”
