Manchester United boss Sir Alex Ferguson left out Wayne Rooney and Rio Ferdinand for their 4-0 win at Bolton Wanderers.
But Ferguson confirmed the pair will be fit to face Bayern Munich after missing out against Wanderers with a bruised heel and a groin injury respectively.
"They were just a bit tender," said the United boss.
"Wayne has a bit of bruising in his foot. If he had played and got a whack on it he would have been doubtful for Tuesday.
"We have a big week. We have to use our squad in situations like this. I have no qualms about that at all.
"They have all done their job well and I will have Rooney and Ferdinand available for Tuesday."
