Evans scored his first United goal in last weekend's 5-0 thrashing of Wolves.
Vidic said: "Jonny has been playing really well in the last few games, as the team has been impressive.
''It's good for the team to have stability at the back and that is the way to retain the title. I remember when I scored my first goal, it's a nice feeling.
''Jonny has come up from the youth team, so it's his dream and it's nice for him.''
