Evra is France's World Cup captain in South Africa this month.
Hidalgo told manutd.com: "He always had the same qualities he has now before arriving in Manchester. But he was not so decisive like he is with Manchester United now. He has developed into a very good defender, very consistent, who also knows how to get involved in the attacking side of play within the team on the left wing.
"He has evolved into a better player, an international player, much more complete. Thanks to Manchester United, he is top drawer now, they have helped make him French team captain, and that says a lot."
