Manchester United striker Louis Saha has been ruled out of the FA Cup final against Chelsea with a knee injury. "Louis is out, he picked up the knee injury in Milan and we did another scan on Monday to identify the problem more clearly," said manager Sir Alex Ferguson. Saha has been struggling since the beginning of the year with knee and hamstring injuries. He missed a big part of the campaign and now he'll miss the FA Cup final. "With Louis now, it is a matter of deciding what to do next. We will be making a decision next week but we are considering an operation." Saha comes at the end of a long list of absentees as Gary Neville has been also ruled out of the game for Manchester while Chelsea will be without Andriy Shevchenko, Michael Ballack, Ricardo Carvalho and John Obi Mikel.
