Rooney will kickoff the campaign at former club Everton tonight.
"It feels like a long time ago," Rooney told manutd.com, although he insists "I'm still fairly young!" when asked if 10 years in the game now qualifies him for veteran status.
"Well, I feel young anyway. It's great to have played in the Premier League for 10 years. It's an exciting league and I still get just as excited by playing football as I did when I made my debut. I just hope I can play for another 10 years and have as much enjoyment as I did in my first 10."
