In a campaign that lurched from peak to trough before settling on the lowest ebb of Manchester City's last-gasp title triumph, Sir Alex Ferguson's young squad is eager to show that lessons have been learned.
Speaking in Fight to the Finish, the club's official diary of the 2011/12 campaign, Rooney admits: "I think we’ve all learned a lot.
"There have been a lot of games where you get a feeling afterwards that you never want to have again, and hopefully we can get hold of that feeling and make sure it doesn’t happen again."
City are expected to reinvest in a bid to retain their title, European champions Chelsea have already enjoyed an active summer and a host of other clubs will vie for domestic rule, but Rooney feels United are ready for the challenge of next season and beyond.
"Just look at all the young players in the squad: they’ve played a lot of games, had a lot of ups and downs and most of them are already getting selected now for their national teams," he says.
"That’s all going to help them. The next two or three years will be a big test for them and I’m sure we’ll all pull through it."
