Wayne Rooney is "desperate" to play on Sunday, but Sir Alex Ferguson still has doubts over the fitness of United's number 10 and his team-mate Darren Fletcher.
Rooney has been struggling with a calf injury and missed the games against Bolton Wanderers and CSKA Moscow in the last week, while Fletcher was also absent for both matches with a foot injury.
"On the injury front I can't give a clear picture, there are still some doubts about Rooney and Fletcher," Sir Alex said on Friday.
Getting the influential pair ready for Anfield is now the main aim for United's medical and coaching staff, though Sir Alex doesn't doubt their eagerness to return.
"He is always desperate to play, that's the nature of the boy," said the boss. "Of course, you can't let that cloud the realistic side of things. It's going to be important how he does in training on Saturday.
"We'll see if Wayne does train on Saturday and then we'll have a better idea."
The good news for United is that Patrice Evra and Ryan Giggs have both been passed fit after remaining in Manchester while the rest of the squad travelled to Russia, but Ji-sung Park has definitely been ruled out.
