#1 The rise of already established mid-table clubs
While Arsenal is in downfall, there are many mid-table teams that are on the rise and can even potentially replace Arsenal in the top six. Leicester City, who were Premier League champions in 2015/16, have had a very positive season. Although they finished 9th, they should be very happy with the personnel that they have at the current moment.
They have a manager in Brendon Rogers, who has previously managed Liverpool and guided them to a second place finish in 2014. The Foxes have a decent squad, with summer signing James Maddison looking like a very shrewd piece of business and loanee Youri Tielemans hoping to be a permanent addition.
Another such team is Wolves. The newly-promoted side already looks like one of the other well established Premier League clubs. Their manager Nuno Espirito Santo looks like a man on a mission. He also possesses a very good squad, with players such as Ruben Neves and Raul Jiminez shining for the club this season and looking as one of the finest players in the league. Their 7th place finish means they will play in the Europa League next season; which is an astonishing achievement for a newly promoted team.
With such teams slowly creeping behind descending teams such as Arsenal, it won't be long until one of these teams climb up the table.
