Nemanja Vidic won five Premier League titles and the 2007-08 Champions League in an eight-year spell at Old Trafford, but conceded injuries had forced him to call time on his career.

Nemanja Vidic joined Inter Milan on a free transfer from Manchester United in 2014 and played 28 times for the Italian Serie A club last season.

Inter Milan secured a 3-1 win over Genoa in to move up to ninth place in Serie A.

United travel to Aston Villa on Sunday for a league fixture that they have not lost since 1995, but with the champions already 13 points behind leaders Arsenal, their grip on the title is weakening.
