Liverpool are amidst their busiest period of the calendar, with Sunday's victory over Everton followed by a midweek clash against Sean Dyche's side.
With such little recovery time between fixtures, it is no surprise that there are a couple of niggling injuries for the squad to contend with.
Robertson, who suffered a dead leg against the Blues, remains a doubt for the fixture, whilst Mane (foot) is unlikely to play a part.
Speaking to reporters at his pre-match press conference, Klopp said the duo would have to be assessed once again ahead of training on Tuesday afternoon.
“Sadio and Robbo we need to have another look at today,” he said.
“Sadio has a really awful cut on his foot, it needed to be stitched.
“It’s OK, but he’s walking in flip-flops and we don’t play in flip flops! Today he’s not ready, but we will see later.
“With Robbo it’s not that serious, but we need to have a look.”
It is likely that Klopp could choose to be on the safe side with both, considering the upcoming fixtures Liverpool have to contend with.
With Mane's injury in mind, Klopp could move things around from Sunday's victory.
