Newcastle's performance was really good at first; I even thought they would win the match, just the way you think, but at the end Liverpool showed them that they are still good and can pull up at any moment. Although you are right, if Liverpool were a weak team, Newcastle would beat them in that match, but they are not. This shows that every club is preparing for this season. It will be an interesting season because many clubs will fight for the title this season. The league just got started; let's see how it will go.
Newcastle did not start this season well, they did not win a match in the first two matches of the season and I think that is very bad even though their defeat to Liverpool is a natural thing because it is realistic when we look at the overall strength of both teams and I will not deny that Liverpool is better and on the other hand Newcastle also deserves appreciation, they played very persistently, it was just a little unlucky because they conceded in the final minutes of the match.
In reality, Newcastle are simply going through an adjustment period with new players and a long break after the league season ended.
So, Eddie Howe shouldn't have any difficulty getting Newcastle back on track and regaining a better position.
Previous losses and draws are understandable, but Newcastle fans are hoping Newcastle will take all three points in their next match.
