His existing contract was not due to expire for another two full seasons beyond this one, but wanted to show his commitment to the club and manager Sir Alex Ferguson now that he has been confirmed as the club's top striker following the departure of Ruud van Nistelrooy to Real Madrid in the summer.

Saha has taken on the Dutchman's mantle with aplomb, scoring 12 goals so far this season.

"It is great news," the 28-year-old Saha told the club's website, www.manutd.com. "I am really enjoying my time here and I wanted to show my commitment to Manchester United and also repay the faith that Sir Alex has shown in me.

"Hopefully we will have an exciting end to the season and add some silverware to the trophy room."

Saha was initially plagued by injuries after joining United from Fulham in January 2004, but has become a key member of the team since regaining full fitness.

Cristiano Ronaldo and Wayne Rooney also committed themselves to United on new long-term contracts recently, so Ferguson has tied all three members of his current strikeforce to the club for the next several seasons.

"I am delighted we have extended Louis' contract," said Ferguson. "We are happy to see Louis here until at least 2010 and to add him to the players who have recently signed new contracts like Cristiano and Wayne.

"We address the situation of players' contracts now and then in order to strengthen the club and it's great to add Louis to the list.

"Louis' form has been fantastic since he has come back from injury and he has scored 26 goals in that time."
