#4 West Ham United
The Hammers looked set to break the top brass after their 7th place finish in the 2015-16 season. However, they struggled to carry the momentum to 2016/17 season and huffed their way to an 11th place finish.
Nevertheless, West Ham still possess a strong squad with Winston Reid, Jose Fonte, Aaron Cresswell and James Collins in defence. The addition of Manchester City legend Pablo Zabaleta brings further experience to the back-line.
Sofiane Feghouli, Cheikhou Kouyate, Manuel Lanzini, Robert Snodgrass and Michail Antonio provide attacking quality from midfield.
Andy Carroll continues to be a threat when fit and Andre Ayew had a topsy-turvy first season at the London club. In manager Slaven Bilic, the Hammers have an astute coach and the side will be looking to perform to their potential this season.
So far, Joe Hart is set to join along with rumoured interests on poacher Javier Hernandez and Stoke playmaker Marko Arnautovic. Each of these signings, if completed, bring a wealth of talent, experience and add further depth to the squad.
Thus, West Ham can be considered a threat for the top six this season. However, question marks over their ability to deliver continue to linger. So, the Hammers have a lot to prove and fight for this season.
