Vidic was with former United boss Sir Alex Ferguson at Wimbledon last week and knows the Scot is close to Djokovic's opponent Andy Murray.
"Sir Alex is a big supporter of Andy Murray and I had a word with him on Wednesday about what it would be like if both he and Novak reached the final," Vidic told Press Association Sport.
"He said he would love that final. I said the same.
"The players are good friends as well. It should be a really good game - although naturally I hope Novak wins.
"He respects any sportsman playing on a high level because of the sacrifices they have made in their lives and all the work they have done throughout their careers.
"Definitely, Novak has done that."
