Sir Alex Ferguson hopes to be able to call on the services of Wayne Rooney for Tuesday's Champions League trip to Galatasaray.
The striker went off injured towards the end of last weekend's win at Aston Villa with an ankle knock, but, after Saturday's defeat at Norwich, Sir Alex revealed to MUTV that the striker missed the visit to Carrow Road because of illness.
United's medical team will assess the England international on Sunday, providing he is well enough to come into training.
"He's had tonsillitis," the boss confirmed to MUTV. "We hope he'll be in tomorrow - we'll see what he's like then.
"If he does [come in] hopefully we can get him ready for Tuesday."
