Speaking to talkSPORT, the Liverpool captain said: "Well, we just lost Darwin, He went to Saudi and we lost Lucho [Luis Diaz], obviously he went to Bayern.
"I think there's always room for an attacker in order to strengthen us so let's see what the window brings in terms of the balance of the team."
THE BIGGER PICTURE
Liverpool's desire to bring in Alexander Isak from Newcastle is well-documented. The Reds' initial bid was turned down by the Magpies, but they are expected to make another offer for the Swedish striker. Isak wants to move to Anfield and would significantly strengthen their front-line, but whether Arne Slot's side will be able to convince Newcastle to part with their key player remains to be seen.

WHAT NEXT FOR LIVERPOOL?
Another bid for Isak does appear inevitable, but an end to the saga does not feel imminent. With the Magpies missing out on all of their alternative striking options to replace Isak, it may not be until late in the window that a deal is sealed.
