Manchester United quartet Robin van Persie, Nemanja Vidic, Shinji Kagawa and Phil Jones are all likely to return from injury for the Champions League visit to Bayer Leverkusen after missing the draw with Cardiff City.
Van Persie has been battling with groin and toe injuries and missed Netherlands' international friendlies, while Vidic suffered a concussion in the win over Arsenal and was rested as a precaution.
Meanwhile, Kagawa and Jones were suffering from respective groin and foot problems and sat out the trip to south Wales, but Moyes insists all could return for the resumption of the Champions League against Leverkusen on Wednesday.
"Robin's groin is the problem at the moment, his toes are much better," the United boss said after his side's 2-2 at the Cardiff City Stadium. "We are hoping to get both Nemanja and Robin back as soon as we can. I hope they'll be in contention for Wednesday but I couldn't give you a definitive answer.
"Kagawa got injured playing for Japan. It's an injury to his foot, there's some bruising there, but it's not too bad.
"Possibly," Jones could return against Leverkusen. "I don't think he is as bad as we first thought. He's not too far away. It's a groin injury, right up his hip."
Moyes' side need a win against Leverkusen to guarantee qualification for the knock-out phase ahead of the final group match Shakhtar Donetsk.
The draw with Cardiff leaves United seven points behind leaders Arsenal after 12 league games after Kim Do-Kyung's late header grabbed a point for Malky MacKay's side.
United were forced to start with Javier Hernandez in attack alongside Wayne Rooney while Jonny Evans partnered Rio Ferdinand at centre-back and Moyes lamented dropping another two points.
"I am disappointed," said the manager afterwards. "Like Southampton, we had it under control with a minute to go but we conceded from a set piece and it cost us.
"We have been on a pretty good run, but that is a blow. We cannot keep dropping two points with where we are.
"We could have played better. We didn't have a lot of rhythm in the second half. I would probably have taken a result however it came today. I would have liked it to be better, but it wasn't to be."
