In October 2003, after American newcomer Tim Howard won the starting goalkeeper's job from Barthez, United agreed to release Barthez from his contract at Old Trafford after the 2003-04 season, and also agreed to loan Barthez out to Marseille for the remainder of that season.
On 8 August 2006, Barthez announced he was still hoping to play professional football for another two years, insisting he was also looking to continue his career in the French international setup.
