Reds assistant Pep Ljinders also confirmed Xherdan Shaqiri would miss the match with a calf injury.
"Yes [Keita may return]. I will not give the team but he is in a really good way… he is an important player, so hopefully we can use him in the next weeks and hopefully tomorrow will be a day where he can shine," the Reds' assistant manager said.
He added: "Yesterday [Tuesday], towards the end of training, Shaq felt his calf stiffen up a little bit.
"He couldn't continue and a scan showed he had a little tear there. We need to wait a couple of days, but for sure he is not in contention for tomorrow. He needs some rest, so he will not be involved."
