The Frenchman has seen his progress at United hampered by a series of injury problems since joining the club from Fulham in January 2004.
Saha started only five Premier League games last season and the 29-year-old has been working hard over the summer as he looks to prove his worth to Sir Alex Ferguson.
"I am a football player, and I could not play so far. Today, only the pitch matters to me," Saha told France Football.
"I have worked all summer long. There were facilities close to my home so I have worked with a specific program. I know what I want - to be fit for resumption.
"I am under contract at Manchester until 2010. Moreover the coach didn't say anything to me yet, neither about a transfer or a loan.
"I don't hide anything. I tell it again: I have to play before thinking about anything else.
"I forecast nothing before knowing what will happen for me."
