Metro: Rojo arrives at United for £15.9m with Nani going to Sporting Lisbon on loan as part of the deal.
The left-sided defender, who is likely to play as one of the centre-backs in Louis van Gaal’s back three, will inherit the No 5 shirt last worn with distinction by Rio Ferdinand.
Rojo said: ‘It is such an honour to say that I now play for Manchester United. ‘The Premier League is the most exciting league in the world and to have the chance to play in it for the world’s biggest club is a dream for me.
