Roberto Firmino had to be ruled out on Wednesday night during Liverpool's match in the Champions League against Atletico Madrid, and the injury appears to be more serious than first assumed.
In any case, manager Jürgen Klopp states that the Brazilian front-runner will not be available for the next many weeks.
There is also reason for minor frowns for the Liverpool manager ahead of this weekend's match. Joe Gomez and Curtis Jones are also out with injuries at the moment, and therefore they will both miss the team's upcoming match this weekend against West Ham.
Also Naby Keita and James Milner are out with injuries, and they are also not with when Liverpool travel to London this weekend.
Jürgen Klopp further tells the club's website that he hopes to have both Naby Keita, James Milner, Joe Gomez and Curtis Jones back after the national team break.
