Jurgen Klopp has offered a fitness update on Roberto Firmino during today's Liverpool press conference
Firmino was left out of Liverpool's squad to face Manchester United on Tuesday and Klopp has admitted he remains touch-and-go for Sunday's Merseyside derby.
Providing the latest on the Brazilian, the German said: "And Bobby, getting better and better. It's just uncomfortable, painful. Today it's his first day on the pitch, so there’s still two days to go, so maybe.
"If Bobby gives the thumbs-up then he will be involved. And not, then we wait another few days, but then I think after that it should be possible."
