Premier League has just run 6 matches, the distance points between teams were still close together, any team still has a great chance to enter the big 4. Wait till januari and the big 4 in the real that will be seen because the distance between club points has started widening, positions 5, 6, 7 and so on will be difficult to pursue the top 4 position in January later until the league ends.
Indeed the real test of tenacity starts in January when the boy's are separated from the men and so everyone had the chance now even though the competition looks like tough already. By January there will be s clear cut distinction on the table.
