United have now won five titles in seven seasons, but many pundits believe the current squad is the weakest in years.
Vidic said: "You cannot make people think differently. They have to believe what they believe.
"I don't think you can judge how good this team was until this generation leaves and another one comes in. I don't have a problem with that.
"I just want to win as many trophies as I can. I am lucky I came to the club at the right time. I am playing with good players and there is a good mentality.
"That is why we have won five titles in the seven years I have been here. That is a good statistic. Hopefully it won't be the last one."
