Sir Alex Ferguson says that Michael Owen will not be in the squad that must face Valencia on Tuesday. The veteran striker returned to training last week after recovering from yet another injury. An injury that the boss thinks he may have caused. Fergie thinks that he may have brought Owen back into the side after recovery from his last injury too soon and he is making sure that it is not going to happen again this time. "Michael has no chance of being involved tomorrow," said Ferguson. "He returned to training in the middle of last week but we are going to make sure he gets two more weeks behind him."We don't want to take any risks because it was probably our fault he was injured last time."
