Newcastle this season are as good as ever, I see no prerequisites to miss the top 4. Liverpool still have a lot of games to play like all the teams in the Premier League, but I'm not sure if Tottenham or Newcastle will want to give their place, besides, I think ten Hag also has plans for the top 4 and he has a good team. Liverpool's chances of being in the top 4 are not that great, although there is a tendency for Klopp's teams to get the peak of their shape towards the end of the season, but whether this will help them I'm not sure.
One advantage Newcastle have over other teams is that the owners are richer and willing to spend more. Saudi Arabia's Public Investment Fund and other co-owners of Newcastle are willing to release more fund for the January transfer window. That means coach Eddie Howe might be able to reinforce his squad next year.
Tottenham's performance reduced in recent time and they lost some important games that made them lose some vital points. Liverpool and Manchester United seems to have solved the problems that limited them at the beginning of the season, so they might come back strong after the world cup break. The only teams that has been consistent this season are Arsenal and Manchester City and I am sure either of these teams would clinch the premier league title if they continue with their recent performance. Tottenham, Liverpool, Chelsea and Newcastle would have to scramble for the other top four position.
