While Kagawa played in both of Japan's friendlies during the international break, van Persie did not take part in either of the Netherlands' games.
"Kagawa got injured playing for Japan," Moyes said at his post-match press conference. "It's an injury to his foot; there's some bruising there, but it's not too bad.
"Robin's groin is the problem at the moment; his toes are much better. 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."
