Liverpool will assess Naby Keita after the midfielder had to be replaced after half-time as he suffering an injury during the Carabao Cup clash.
Keita was replaced by 18-year-old Curtis Jones.
"If Naby's injury is not so serious, which I hope, then it was a nearly perfect night," Klopp told Liverpoolfc.com .
"He felt a little bit. I saw it, he slipped when he lost the ball. Afterwards he was limping a little bit and he said it was 'ugh'. Hopefully it's not too serious. We'll see."
