The reigning champions have endured a turbulent 2013/14 campaign, with little resistance offered as the top flight crown has been snatched from their grasp.
A top-six finish is the best they can hope for now, with a succession of setbacks having cost David Moyes his job just 10 months after he was charged with the task of picking up the baton put down by the retiring Sir Alex Ferguson.
United stalwart Giggs has been handed the reins on an interim basis, and he got off to a winning start on Saturday as Norwich City were swept aside 4-0 at Old Trafford.
It remains to be seen whether he will be the man asked to rebuild in the summer - with Holland coach Louis van Gaal still a strong favourite to land the role full-time - but Giggs believes that whoever is charge next term will have a squad capable of competing for major honours.
He said: "We've got everything in place to have a successful season next year. We've certainly got the players.
"It's going to be hard, obviously, because we've had a tough season and obviously the lads at Liverpool have improved and other teams around us have improved.
"It won't be easy, but I'm confident."
He added on claims that United are now a side in decline: "We won the league last year. The year before we lost it on goal difference, the year before that we won it.
"Where did Liverpool come last year, seventh? Who would have said they would be where they are this year, so a lot can change."
For now, Giggs' focus is locked on ending the current campaign as positively as possible - with the Welshman having entered the unknown by accepting a temporary managerial post.
He added: "I have obviously been here a long time and I know the ins and outs of the club, but there's so many other things I never knew about because I've never been in this position before.
"They all add up during the day and they all add up during the week and it's tough. But I'm enjoying it."
