The Reds face Fulham on Sunday as they look to continue where they left off from in Munich on Wednesday night.
Klopp's side will be without skipper Henderson, after the midfielder was forced off the pitch with an ankle injury in the opening 15 minutes against Bayern.
Speaking at his pre-match press conference, Klopp confirmed that Henderson would miss the encounter, although he should be back fit after the international break.
“We’ll have to see still. With Hendo we made further assessments and it’s serious enough to rule him out for the weekend,” he explained.
“The international break will be long enough hopefully to bring him back, but it’s obviously a little one with the ankle, how it looked in the first place.
“So it was the best we could get but still not good enough, that’s was clear. Not good, but OK.”
Klopp also provided an update on Keita's fitness. The Guinean missed the trip to Munich with a minor injury and remains a doubt for this weekend.
“Naby we have to see if he can train today, the boys come in a bit later today and we have a couple of checks,” he said.
“It’s positive now, but we have to see if it stays positive when he goes outside.”
The boss was also questioned about Oxlade-Chamberlain's latest injury set-back after he came off with a hamstring complaint on his return for Liverpool U23s.
“Oxlade I heard nothing new about it but there’s no rush now,” he said. “For sure after the international break he will be 100 percent fit.”
