The Argentine winger is on the verge of completing a British record move from Real Madrid, and Macheda believes his arrival will give everyone a boost.
Macheda, now at Cardiff City, said: “I think he's one of the best signings they could make. At Man United a player like Di Maria will lift the players and the club as well. If they can get him it will be great for the club.
"He has played already for a big club in Real Madrid so he will be fine with the pressure on him.”
