The imposing Dutch defender's transfer went through on Tuesday, and today we release his first full interview as a United player across our platforms.
It's a must-watch, in which the 25-year-old discusses his hugely impressive career to date, at three of Europe's truly elite clubs: Ajax, Juventus and Bayern Munich.
De Ligt also discusses playing with Cristiano Ronaldo, his relationship with Erik ten Hag, plus the leadership qualities he feels he can bring to the Reds' defence.
But perhaps most interesting to United fans everywhere will be De Ligt's reasons for joining, as the club embarks on its first full season since Sir Jim Ratcliffe became co-owner.
