The Reds could struggle to qualify for the Champions League after a horror run of results since the turn of the year.
Injuries have wreaked havoc at Anfield, but Klopp has urged the club to stay optimistic about the future.
"I always expected the season would be like this," said Klopp, via the Liverpool Echo.
"I didn't expect that we would have the injury issues we have in one critical position, but I knew that it would be a campaign where it would be a proper race until the very last inches as we approach the finish line.
"Keeping faith in yourself and those who care about helping you is absolutely vital. It's being tested of course - difficult times do that, for all of us.
"I refer to all of us in the LFC family: the players, the supporters and me and my staff also. All of us.
"We have been such a strong unit since I came here - we came together to help each other and it produced wonderful moments we will have forever. But it's more important now than ever before.
"We haven't lost it, by the way! No chance we will lose it, but it's always worth reminding ourselves how important it is to what we look to achieve."
