Few could have imagined the woeful season that would follow Barclays Premier League glory in the last of Sir Alex Ferguson's 26 years in charge
Ferguson's replacement David Moyes did not even last a season at the helm and, after a miserable seventh-placed finish, Van Gaal has been tasked with changing United's fortunes.
The Dutch manager will take charge after leading his country at the World Cup and Rooney is looking forward to working under him and assistant manager Giggs
"I think it is a great appointment," Rooney said
"I think everybody knew for the last few weeks that Louis van Gaal was going to take over and the record he has got around European football is fantastic.
"He has won a lot of major trophies and it is great that it is sorted out now.
"It is obviously great that Ryan has stayed with him as his number two
It is exciting and it is going to be an exciting time at the club."
