Liverpool stars Roberto Firmino and Naby Keita are doubts to face Watford on Wednesday night.
The Brazil forward was substituted with an ankle injury in the first half of Liverpool’s goalless draw with Manchester United on Sunday.
Meanwhile, Naby Keita missed Monday’s training session through illness.
Liverpool boss Jurgen Klopp admits his side have been lucky not to lose Firmino for an extended period of time.
He said: “He looks good, we were obviously lucky. It is not as serious as we thought in the first moment, but if Bobby leaves the pitch it is not a good sign.
“We play tomorrow and it will be very close for that, but there’s still a chance for the derby (against Everton on Sunday).
“Because it’s Bobby, I would say ‘yes [there is a chance for Watford]’, but I don’t know if I would use that chance.
“Writing Bobby off is a big mistake because he recovers very quickly.”
Klopp added: “Naby was ill yesterday, unfortunately, but I’ve heard now, I got a message, that he is back for today. We have to see how he is.”
Liverpool will be without Dejan Lovren (hamstring) and Joe Gomez (leg) when they host the Hornets.
The Reds lead Manchester City at the top of the Premier League by one point with 11 games to go.
