Manchester United chief executive David Gill is confident winger Cristiano Ronaldo will sign a new deal, which will take him up to 2012.
Ronaldo has been in stunning form this season
Ronaldo, 22, is under contract until 2010 but is keen to extend his stay.
"I think he came out and said discussions are ongoing so we're not going to put a timeline against them," Gill told BBC Radio Four.
"The player wants to stay, we want him to stay and I'm sure we'll reach a satisfactory conclusion."
Ronaldo has been linked with a move to Spain and the Portuguese international admitted he would like to play in La Liga before the end of his career.
But Gill added: "Every United fan can be reassured he won't be leaving this summer.
"It would be realistic to extend it by a further two years to 2012 - the same time that Wayne Rooney has signed for."
In response to United manager Sir Alex Ferguson's comments at the weekend that he would be happy to stay for another two years, Gill added: "We're doing extremely well this season.
"We've not discussed it but he has done fantastically well and we've put him on a rolling contract - something we want to continue as long as possible."
