All the teams have close points to each other now,we will wait till January to see the team that will be more favourite to lift the EPL trophy this season.
I quite agree with you the gaps between them are just small, it going to be difficult for someone to decide so so club will lift the trophy, for instance Manchester City that is on the top of the table are leading the second with just a point while third place and fourth place had the same point which are just left behind with two points between them and second place and right now the top four on the table are all in form which am expecting one of them to be champion.
It's very difficult to start speculating who will be able to win the title this season. Apart from the fact that the points gap between them is still very tight, in terms of play and performance there is no significant difference between them. We'll see who will be more consistent between them until the end of the season.
Tottenham have been very consistent since the start of the season, in fact they also slipped in week 11 by losing to Chelsea with a landslide score too. Even though we know Chelsea's current situation is not better than Tottenham, they can play better in that match.
