Manchester City is a team that tends to put pressure on Arsenal rather than the other way around. I don't think Arsenal can take first place from Manchester City if in the next match they fail to win the match against Tottenham. Of course Arsenal and their fans are very confident in the possibility, but in fact Arsenal failed to have a good mentality in the title race last season.
The matches against Tottenham, Manchester City, Chelsea and Newcastle in the coming weeks will be a benchmark for whether Arsenal deserves to lead the standings, but I really doubt that Arsenal can take it from Manchester City easily.
There is always luck in attempting, and that is what makes a team stand out from the other teams. Taking over first place in the standings from Manchester City is no simple task. They have been doing admirably, which has earned them this position. Arsenal is also attempting to close the gap they have made between themselves and Manchester City, which will assist them achieve their goals faster when the time comes.
