These are the few reasons why the upcoming season of the English Premier League could be one of the most thrilling seasons in recent memory.
Chelsea will find it hard to successfully defend the title that Antonio Conte won by seven points in his debut season in England. When you also have the players he has, that makes it a massive challenge for us.
Mahrez was on Arsenal's radar last summer fresh from his exploits to help Leicester win the league title, but he chose to remain at the King Power Stadium for another season agreeing to a new deal until the summer of 2020.
Manchester City will travel to Brighton at 16:30GMT.
Morata contributed 15 LaLiga goals despite starting only 14 league games for Madrid last season and Chelsea need him to make an immediate impact, with star man Eden Hazard out for the opening weeks as he recovers from an ankle injury. Their stock has plunged so dramatically they can be backed at double figure odds to win the title this year and are fifth favourites in the outright betting behind Manchester City, Chelsea, Manchester United and Tottenham.

Chelsea manager Antonio Conte has insisted he is not looking for sympathy from Arsenal boss Arsene Wenger.

The France striker netted as Rennes were beaten 2-0 a year later and, although Lorient shackled him in 2015, the 26-year-old punished Nancy with a hat-trick last term. Alexis Sanchez will be missing with an abdominal strain, whilst Mesut Ozil is also doubtful. That tally for Arsenal was the worst in the big six, and also poorer than Southampton, Everton and West Brom.
It might take a little bit of time before he can lead the line for Arsenal but playing just off he can be just as effective.
