Liverpool are hopeful that Divock Origi will return to full fitness soon, but they are taking caution due to the recurrence of an ankle injury that has plagued the Belgian for several years.
Origi hasn't played for Liverpool yet this season after spending the last campaign out on loan at Wolfsburg, and he was sidelined while playing for Liverpool's Under-23s earlier this month.
"Divock is not far away but it’s an ankle thing and a very unfortunate situation," Klopp told Liverpool's official website.
"We will be very careful - the ankle was the problem he had after the Everton game years ago. He will be back, I’m pretty sure, next week but not now."
However, there is good news for Liverpool as Dejan Lovren is now available for selection again following a pelvic injury.
The Croatian has not played any competitive football since the World Cup final but Klopp confirmed that he is back in contention.
"Dejan looks actually quite good. He trained completely normally now four times," Klopp added.
"He had a very intense period before that; he trained with the fitness guys already for 10 days or so before we took him then in normal training. So he looks ready."
Dominic Solanke is also back in contention and could play a role against Chelsea in the EFL Cup on Wednesday, but Adam Lallana will not be risked.
