United lost three players - Ander Herrera, Juan Mata and substitute Jesse Lingard - to injury during the first half of Sunday's 0-0 draw with Liverpool at Old Trafford, while Nemanja Matic did not start the match.
Additionally, there were concerns over Marcus Rashford, who appeared to limp through much of the game after receiving a heavy challenge in the first few minutes.
“Well, the three we had to take off [Herrera, Lingard, Mata], they're not going to be ready,”
Solskjaer told MUTV.
“As for Rashy [Marcus Rashford], we're going to work on him for as long as we can to see if he gets ready because that wasn't as bad as we first feared, so luckily I don't think we damaged it any more by him finishing the game.
