I see Newcastle now like Manchester City before Haaland was there, all the players are the same and also there are no top players or core players, but they are able to play solidly and also go up and down evenly.
and what you need to worry about is, manchester city because they are only 2 points away from newcastle in my opinion newcastle can overtake them if their game performance is consistent.
and it looks like Newcastle can beat Leicester City because the difference in the standings is far in my opinion also has an effect.
I wouldn't worry about that because basically Newcastle haven't proven themselves better when the opponents are stronger on paper. But if Newcastle can beat Manchester United, Manchester City, Liverpool, Tottenham, Chelsea and Arsenal then I will be worried. But now I wouldn't really worry about them even if the point gap was only 2.
Even so, I think Manchester City also needs to maintain its performance considering the season will be very busy. Manchester City can also be overtaken by other teams including Newcastle and Tottenham. So they have to be really careful about those bad possibilities.
