Sturridge scored the opener at the Olympic Stadium, and looks set to retain his starting role at Anfield on Sunday, with Liverpool seeking a Champions League place.
But speaking at Melwood on Friday, Klopp revealed that Firmino’s recovery was on a “positive” bent, suggesting he could return to the fold at Anfield.
“[It’s] very positive. We could not decide until now, but he feels good,” he told reporters.
“He’s not part of team training, we will make a final test tomorrow and we will see.
“I would rather say yes [he could be available], but not sure.”
“It’s not that difficult an injury, it’s difficult to make the rehabilitation. It needs time,” he said.
“At one point you think ‘it would have been better if he broke his leg’!
“We’ll be without him on Sunday, but no concerns [about long-term problems].
“The season was a little bit short to come back, that’s for sure.”
