Flocking to Twitter, many Liverpool fans can't believe their bad luck as more injury news is confirmed, this time for striker Roberto Firmino.

Reds manager Jurgen Klopp has had to cope with mounting injury problems in his squad recently, akin to the issues he was having last term, as he now sweats on six players in total.

Before Firmino's setback, Liverpool already had five players sidelined for the trip to West Ham today with James Milner, Naby Keita, Harvey Elliott, Curtis Jones and Joe Gomez all unavailable (This is Anfield).

Confirming yet more injury news, Klopp has said that Firmino, who already has six goals to his name this season, has been added to the list after he sustained a 'serious hamstring injury' (Liverpool FC on Twitter).

"Bobby is not good news with a serious hamstring injury, really unfortunate,” Klopp said.

“Losing Bobby Firmino is a blow. It’s weeks and I don’t know exactly but more than four which I would consider a serious injury. We have to see, Bobby is a quick healer.”

Flocking to this news, it's little wonder so many Reds supporters are livid given that they are slowly running out of options with the Africa Cup of Nations also on the horizon, when they will lose the in-form Mohamed Salah and Sadio Mane.

Check out some of the reactions from Liverpool fans below as news of Firmino's injury was revealed by Klopp.
