The Reds take on Bayern in the last 16, with their opening clash coming at Anfield on February 19, and have spent the week in Marbella preparing.
But Klopp has revealed that Wijnaldum is now likely to be cleared for the next game, which is a major boost after his man-of-the-match performance against Bournemouth.
“Gini didn’t train yet, that’s of course not cool after a very intense game for him,” he told the club’s official website on Thursday.
“So he had a little dip, but will start today so that’s good.”
Lovren is still yet to make his comeback from a hamstring injury, and according to the Mirror‘s David Maddock has undergone treatment abroad this week, but will report to Melwood on Saturday.
Klopp explained that if Lovren then gives the green light, he will consider him an option against Bayern.
“I don’t want to rule it out but I cannot really plan with it,” the manager said.
“He is not here for good reasons, because he cannot be part of training.
“We are back on Friday. Then from Saturday on, Dejan is back at Melwood and we will see.
“But, of course, we have to prepare it differently. If Dejan gives a sign on Monday—’I feel brilliant’—then we’d have to think anew.
“But in the moment we prepare the game and in this preparation Dejan is not involved. We have to find other solutions.”
