#5 Nemanja Vidic
We are opting for Nemanja Vidic in our list, though his defensive partner Rio Ferdinand also left Manchester United in 2014 on a free transfer.
Vidic was one of the most feared centre-halves of the last decade. He was an ever-present figure of the Manchester United team that dominated the Premier League under Sir Alex Ferguson.
At Old Trafford, he won a total of 15 trophies including - 5 Premier League titles and one Champions League trophy, while also claiming two Player of the season awards.
At the age of 33, the Serbian decided to move out of England and agreed to an Inter Milan move in 2014.
Though he was clearly past his prime he fought for his spot in the Inter squad and made 23 league appearances, even scoring with a header in the process.
The free transfer of the player was a mutually agreed move between the player and the club and thus his spell with the club ended without any bitterness.
