"It's great news.
"I'm 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."
"I'm delighted we have extended Louis' contract.
"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 Ronaldo and Wayne Rooney but also to the new additions such as Patrice and Nemanja. It bodes well for the future. 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.
