You are very right, Tottenham is doing incredibly well, far much better than i ever expected, but i still hope the leave they will drop a bit for Arsenal to take that first position in the EPL table, their next game is with Fulham, and it already expected that they (Tottenham) may likely win that game effortlessly even though we can't really underrate Fulham.
Both clubs have maintained same number of points for some time now, and personally, it looking like they both may still continue to maintain same points even after their coming game, since Arsenal will be facing Chelsea, and it is already expected that they will beat Chelsea, and if Tottenham also beat Fulham, both teams will still come out with the same point, waiting eagerly to see which of this two clubs will give way for the other.
Premier League Round 9
Arsenal have a tougher game to go through than Tottenham Hotspur. All these games are also London derbies, I do not expect easy wins from any of them clubs.
Arsenal would be away trying to break down Pochetino and his lads finding them way to the top after three successful wins with two coming from the Premier League games.
Tottenham Hotspur against Fulham! This also would be a tough derby, they've both met this season on the 29th of August with the game ending as a draw. Fulham though got to win on penalties to knock them off during the EFL Cup Competition.
To make it safe both Tottenham Hotspur - Fulham and Chelsea - Arsenal should end as a draw. Lol.
Finally, Tottenham Hotspur and Gunners are my final predictions to take three points home.
