"Individually we've done well, and as a group we've helped each other and that's shown in our results."
He added: "I've had great times here in terms of winning trophies and playing in big games, but I've also had bad times with injuries. I've been lucky enough to win a lot of medals and hopefully that will continue this season and beyond.
"The 1998/99 season seems like such a long time ago, too. It was my first main season in the first team and it was amazing to be a part of such an achievement.
"If we could achieve something like that again during my time here, it would just be unbelievable."
Brown has often had to play second fiddle to Gary Neville both for United and England, but with the veteran full-back injured all season he has grabbed his chance with both hands.
He added: "For me, this season, it's been amazing to be playing.
"I've not been injured and I've been getting games under my belt and getting used to playing week in, week out. It has been great to play so many matches and I think I've done okay.
"It was only really because Gary got injured that I've been a regular this season, but playing every game helps you improve and gives you more confidence - I've definitely discovered that this season."
