West Ham arguably have the easiest final five fixtures on paper out of all the teams battling for the top four.
The Hammers play 14th placed Burnley, 8th placed Everton, 17th placed Brighton, 19th placed West Brom and 15h placed Southampton, which gives them a great chance of picking up a significant number of points.
In contrast, Chelsea, who currently occupy fourth spot, have a far trickier run-in. The Blues face 18th placed Fulham next weekend, before taking on table-toppers Manchester City, Arsenal (10th), Leicester (3rd) and Aston Villa (11th). They also have two Champions League semi-final legs to play against Real Madrid over the next ten days.
Liverpool do have a difficult fixture against 2nd placed Manchester at Old Trafford, but the rest of their games are against teams in the bottom half of the table. In their final four matches, they will face Southampton (15th), West Brom (19th), Burnley (14th) and Crystal Palace (13th).
Although Chelsea are currently three points ahead of West Ham, their run-ins suggest that the Irons may well be able to close the gap on their rivals. It will be interesting to see how the last month of Premier League action unfolds.
