I think Arsenal might be champions this season with there performance and as the season just started those at the top like Manchester city will have pressure maintaining the top and will face heat from the top four and when they drops points definitely other teams will want to reach the top cause the top four is tight presently and with the way the Arsenal squad are playing I believe they can defeat Manchester city
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.
