United has had a woeful campaign by its lofty standards, surrendering the league crown with a whimper, currently sitting behind table-topping Liverpool by 20 points.
After David Moyes was sacked for overseeing the Red Devils' steep decline, Giggs started his tenure as temporary boss with a 4-0 triumph over Norwich City at Old Trafford on Saturday and the Welshman believes that squad is good enough to bounce back quickly.
"We've got everything in place to have a successful season next year. We've certainly got the players," the veteran midfielder told reporters. "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."
When asked if United was on the decline, Giggs responded: "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."
