Torygraph:
Tevez has trained on a daily basis with his new United team-mates since his representatives agreed to pay West Ham a £2 million compensation package last Friday and he had been pencilled in by Ferguson to make his first appearance in a United shirt in a friendly at Dunfermline Athletic.
However, United are unable to field the player until his registration has been transferred to them from West Ham and club officials now fear that the paperwork will not be completed until tomorrow.
While Tevez is on standby to fly north of the border should his registration be processed this morning, the 23-year-old is now more likely to have to wait until the Premiership opener against Reading at Old Trafford on Sunday for his debut. Ferguson said: "Tevez has already looked quite sharp in training and it would be nice to think that he'll be ready for the Reading game.''
