Since Emery came things have been completely different for Aston Villa. They are like they have been touched by a magic wand. Because Emery's system has been running like clockwork. They are even a title contender at the moment. Especially after defeating Manchester City by not letting them even play and defeating Arsenal right after that was enough to see them as a title contender for now. 
However consistency is always the key factor in this. Emery is currently the most impressive manager in the league undoubtedly. If he goes on like this he would deserve to take the manager of the season prize.
Yes, that's right, no one even thought that Aston Villa could beat Arsenal and Manchester City and try to get rid of these two clubs from the top ranks. Currently, Aston Villa is getting closer to first place and is only 1 point different from Arsenal, 2 points from Liverpool, this season. It will be a very interesting match to see Aston Villa trying to put pressure on Liverpool, Arsenal and Manchester City. I think that if Emery can bring Aston Villa to become Premier League champions this season, it will be an unexpected achievement for Aston Villa, but Aston Villa must maintain its consistency if they want to win the title this season and that is not easy, they still have to play many matches in the Premier League this season. I hope Aston Villa can maintain a good record not only in home matches but also in away matches because coincidentally Aston Villa can beat Arsenal and Manchester City at home.However consistency is always the key factor in this.
