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.
