After receiving a number of tweets from supporters asking if he was on his way out of Old Trafford yesterday, the England striker laughed off suggestions he was to be sold.
Rooney posted on Twitter: "Haha these rumours are false. I've said before I'll be at United for a long long time."
This is not the first time Rooney has been linked with a move away from United in recent weeks, with speculation earlier last month claiming the 26-year-old would be shipped out after a disagreement with Sir Alex Ferguson.
However, these reports were denied by both parties, and Rooney has confirmed he wants to stay with the club for as long as possible.
Rooney has missed the last two games for United, having sustained a calf injury in the win against Arsenal at the Emirates Stadium in January.
United won in his absence on Tuesday night, beating Stoke City 2-0 at Old Trafford to draw level on points with Manchester City in the pursuit of the Premier League title.
City lost 1-0 to Everton at Goodison Park, with former United midfielder Darron Gibson netting the only goal of the game.
