Obviously Klopp can use Firmino to replace Nunez for a while, but I think he can also use other players like Jota
Jota is probably the best choice that he has right now. Jota has been great since last season, well he is probably not on the same level as Salah or Mane last season but he was one of the reason they scored on some important games last season
Anyway, I will be happy if we can atleast hold Liverpool in Old Trafford. Pretty confident that we cant win because we suck so bad in the first two games against those low tier club so as long as Liverpool doesnt get 3 points in Old Trafford then I'd consider that as a decent result
