United have rebuffed two bids from Chelsea for Rooney, who missed the 2-0 FA Community Shield win over Wigan with a shoulder injury, but could still feature for England against Scotland at Wembley on Wednesday.
And Vidic hopes the England forward will still be at Old Trafford following the closure of the transfer window on September 3.
"I believe Man United is the biggest club in the world and I think there's no point to go anywhere," Vidic said.
"There's so much speculation, so much talk about whether he'll leave or stay. He's at the best club in the world.
"I have to say the last four years I was in that position as well. People were talking about me leaving the club.
"I'm still here and I'm enjoying playing for this club. Nothing has changed."
Moyes insisted there is no rift between himself and Rooney, who has not featured in pre-season due to hamstring and shoulder concerns, while stressing his wish that the striker's involvement with Roy Hodgson's squad aids United.
He said: "Roy knows the situation. Wayne has trained. Some of you (the media) might not like hearing this but I didn't fall out with Wayne.
"Wayne trained with the reserves because it was his asking. He couldn't have contact, it was a shoulder injury and we used him as a floating player which means he doesn't play in either team, he plays between them both.
