For Liverpool this season, especially at the start of their season, it's not going well so it's a little more difficult than one might imagine.
Their performance is quite inversely proportional to last season plus the injuries to several players at the start of the season such as Jota's injury and most recently Diaz was another blow after Salah or Nunez still couldn't contribute properly.
In the last season, they had to play too many matches which affected their performance in this season. Klopp was too optimistic after lost in Champions League final match last season. He did not imagine that season will make his players tired physically.
Nunez will play very important role in Liverpool after World Cup. He will be a most second important player in Liverpool attacking, after Mohamed Salah.
I might be reluctant to say that it is difficult for them at the moment, it tends to be impossible to see them win but it is still possible to see them in the top 4.
Top four is in their hands but load of works must be done by Liverpool. They have disadvantage to other competitors so they must work harder in rest of season.
