Van Persie made the controversial switch from Arsenal to the Red Devils, and the Frenchman revealed that the move was a shock for him.
Evra, who has been working as a pundit for the network during this summer's World Cup in Russia, revealed that he used to refer to Arsenal as a 'baby club' to the Dutchman, who took the comment light-heartedly.
"he understood straight away because I remember him saying: 'Patrice, to be fair, I just feel like now I’m playing for a big team because all of you win many trophies, many medals, and you still go in the gym before training, going in the gym after training'
"Robin was like a kid, he was just like amazed about that".
The striker, however, adapted quickly to his new 'man's club', helping United to reach the Premier League title in 2012-13 with a golden boot-winning 26 goals in his debut season.
Evra has an unorthodox style to punditry, and came under criticism for applauding the analysis of England international Eni Aluko ahead of Costa Rica v Serbia.
The former French international, who has just been released by West Ham, has also been quick to come to the defence of his compatriot Paul Pogba, who has come under much criticism recently.
