Manchester City always has a surprise at the end of the season, that's why whoever is at the top of the standings, don't rejoice first because in the end it is Manchester City who will win the title this season. If you really want to win the EPL title from Manchester City, of course Liverpool can maintain their consistency until the end. season and play as best as possible to stay on the winning path until the end of the season.
It is not yet certain that Manchester City will win the Premier League this season same as either Liverpool or Arsenal; there will be a lot of surprises in the second phase of the season because most team’s performances will improve because they will sign more players this January. After this January, we will know who will be the champion in the process.
Arsenal's failure last season is an important lesson, not long ago Arsenal always played well and consistently but for some reason they failed to get a win from the last two matches they lost in a row which made them lose points and fall from the top of the standings, that is what Arteta must learn that Arsenal need lots of good players to be able to play to replace injured key players. The competition for the top four is very tight which is why this season looks very interesting to me.
I hope these two consecutive losses in their last matches will be the end of they really want to be title contenders. This season will be different if Arsenal sign a striker and a full back to support Zinchanko if Tomiyasu is injured; this will help them improve in their performance in both Champions League and the Premier League.
