Sir Alex Ferguson has announced that Rio Ferdinand and John O'Shea are fit and will start the match against Inter Milan tomorrow night.
Ferdinand left the pitch injured during Saturday's 4-0 stroll past Fulham in the FA Cup and it was feared he might not be ready to play against Jose Mourinho's team.
However, Ferdinand took part in full-training this morning, while O'Shea has also reacted positively after treatment to a heel problem.
"They are both fit and they will both play," said Ferguson.
"They both trained for the first time this morning and that was important for us."
Ferdinand will partner Nemanja Vidic in central defence. The Serbian defender was suspended for the first-leg but returns following his one-match ban.
