Ferguson - We must keep working hard
The landmark was a special one for the United boss but in an interview in the club's official magazine he says he has no thoughts of taking it easy.
He told Inside United: "There's a responsibility as the manager of Manchester United. It doesn't go away. I'm not going to take it easy because we won the title. Hopefully we'll be better next season. The only thing you can do at this club is win - that's all that matters."
Ferguson added: "We have to carry on, there's nothing else you can do. We have a responsibility and expectation to live up to and that carries on next season.
"As I've always said, Manchester United should accept a challenge. We're good at that and, next season, we'll accept anything that comes our way."
Ferguson reiterated that the 19th title was particularly special.
"It's a great feat winning this league, it was Liverpool's time in the 80s, it's our time now," he said. "This was a particularly special one because it means we've won the title more than anyone in the country. It's history and it's great for the tradition of this club.
"The players have been great, I think they deserved it because there were a lot of great performances. I'm dismissing all that nonsense that it's not a great Manchester United team."
Ferguson also described United's Champions League conquerors Barcelona as the best side they have ever played.
He added: "They are at a tremendous peak in the cycle of their team - you get teams who elevate themselves to that status and I think Barcelona are that team. We were well beaten."
