Good games and plenty of goals today. Liverpool won comfortably. Chelsea lost at home, bad start goes on. Great London derby is over with draw but nobody talk about Newcastle here? I'm surprised it's missed by many people. 
Newcastle United scored 8 goals against Sheffield United in away game. It was a big disaster for home team. Sheffield United only have 1 point in first 6 games, it looks like they will go back to Championship quickly. With that squad they don't have much chance anyway, team quality is below average for Premier League. Burnley and Luton Town also are pretty weak teams and probably they will be relegated as well. Normally we don't see this much difference between Premier League teams but these three were way below others quality.
Newcastle had a far-fetch history against shuffled United. The Shuffled United team suffered a humiliating loss by a score of 8 goals, leading some to wonder if there were no goalkeepers or defenders on the team.

By the end of the season, I think it's possible that Luton, Burney, and Shuffled will be relegated back to the league from whence they originally came. As you noted, they are way below other premier league clubs in quality of players.
