"They can go on as much as they like - that's what you would expect - but the history of our club stands us aside," Ferguson said.
"We don't need to worry about that. I think we have a rich history, better than anyone and it'll take them a century to get to our level of history."
"It's a fantastic achievement. This is not an easy league. It's the hardest league in the world, and anybody that wins it deserves it.
"At the start of the season, if I remember correctly, I said 82 points would probably win the league this season and we are seven points ahead of that. But look, it doesn't matter, we've lost the league.
"It is a cruel way to have the title ripped away, but I've had a lot of ups and downs in my 25 years here.
"There will be times when we can sit back and say we did this wrong, we did that wrong, but 89 points would have won the league most seasons."
Manchester United manager Sir Alex Ferguson said on Monday he wasn't concerned by rivals and newly-crowned Premier League champions Manchester City's ability to out bid them in the transfer market.
