Dejan Lovre was not among Liverpool’s travelling party as he remains out, having suffered a hamstring blow against Wolves in early January.
Klopp told Liverpool’s official website of Lovren’s absence: “Dejan is not here and Joe [Gomez] is not here.
“That’s never a good sign, I would say, but we will try everything to make Dejan available for Munich. It will be a tight race.
“For him, it makes sense at the moment to be in another place to do what he has to do. It wouldn’t have helped if he was here, so we will try everything – that’s clear.”
James Milner, Georginio Wijnaldum and Fabinho all sat out of training on Tuesday, but Klopp insisted this was purely due to precautionary measures.
“None of them are serious, all will be fine,” he said.
