The Reds fly to Greece on Monday for the first leg of the last 16 encounter on the back of a convincing win at Crystal Palace thanks to second-half goals from Robin van Persie and Wayne Rooney.
Evans, Jones and Rafael all missed the victory in the capital but United still kept a clean sheet.
"We’ve got a few injuries but I’m hoping we might get a few of them back for Tuesday," stated the boss. "We’ll get a chance to see how Jonny Evans, Phil Jones and Rafael are on Sunday and see if they can join us.
"We’ve got a tough European game coming up on Tuesday now. I wanted to win [at Palace] so we could go into it in form and with confidence. It’s such a big game for us. We hadn’t played for 10 days before Saturday, so I wanted to make sure all the players were ready and will be ready to perform again on Tuesday."
