Liverpool manager Jurgen Klopp has conceded that Roberto Firmino will not be available for Saturday's Premier League clash with Newcastle United due to a foot injury.

The Brazilian has now missed the Reds' last three games in all competitions with the issue and was not ready to make his comeback in the Champions League triumph over Villarreal.

Firmino's injury is not a serious one, but Klopp has admitted that the forward will be out for slightly longer than anticipated, while an update on Curtis Jones and Kostas Tsimikas was also offered by the Reds boss.

Speaking to reporters in his pre-match press conference, Klopp said: "With Bobby it's not a serious injury but it takes a little bit longer than we all thought and longer than he thought.

"He will not be ready for tomorrow, hasn't trained yet. We will have to find out more information. Kostas and Curtis had a couple of issues. Kostas was back training yesterday but Curtis is not yet back."

Liverpool can temporarily leapfrog Manchester City at the top of the Premier League table with victory on Saturday before the reigning champions take on Leeds United a few hours later.
