Liverpool players are not performing well. Nunez was brought in as a replacement for Sadio Mane, but he has yet to prove his worth. Nunez needs some time to adapt to the Liverpool team, I don't think Liverpool's performance will improve if Nunez doesn't play well. Nunez and Salah will need to perform well if Liverpool is to improve. If this duo doesn't play well, it doesn't look like Liverpool will be able to challenge for the title this season.
Nunez will try to do his best this season at Liverpool even though at the moment Nunez is still not showing his good abilities, but I still really believe that Nunez is very capable of adapting quickly and also showing good abilities this season for Liverpool so that the team can be in on the title challenger path again this season. I see that Nunez and Salah are a very good duo at Liverpool, so Liverpool's performance will not go away this season either.
