In the build-up to the 2017/18 Premier League season, Chelsea's summer transfer window business has been a bit of a mixed bag to say the least. On a positive note, the Blues have bolstered their squad with the likes of £70m record signing Álvaro Morata, midfield prodigy Tiémoué Bakayoko and powerful defender Antonio Rüdiger. However, while the Blues have long been notorious for being as enthusiastic about lending their goods as a daytime TV advertising payday loan company, the Premier League...
The Leicester City winger is one of the most exciting young talents in the country, and made a real name for himself with his performance in England's solid U21s European Championship showing earlier in the summer.
The likes of Spurs and Everton are thought to be keen on the pacey youngster, who's fearless approach to the game is tailor-made for success in the Premier League. Chelsea could snap up a real gem in Gray, who perhaps needs a break alongside players of a higher standard.
Having developed into one of England's most consistent defenders, Danny Rose has grown into a top-class player. One of the first names on his country's team sheet, the 27-year-old is now in his prime.
The pacey wing-back is believed to be open to a move across London to Chelsea, having publicly addressed his dissatisfaction with his current wage packet at Spurs. The Blues have the resources to more than double Rose's wages, but admittedly his club are unlikely to sell to a fierce rival.
Before Bournemouth striker Callum Wilson suffered a cruel cruciate ligament injury last February, the 25-year-old was establishing himself as a Premier League-quality striker.
While signing an injured player is always a risk, Wilson is a player worth taking a gamble on, given that he wouldn't be the first choice striker at Stamford Bridge and would have the time needed to rehabilitate.
With Chelsea down to just Álvaro Morata and Michy Batshuayi, Antonio Conte needs a back-up striker before the transfer window ends.
The rags-to-riches, slow-burning saga of Jamie Vardy has been so compelling that it has even been muted as suitable fodder for a Hollywood blockbuster, and it feels like the striker may just have a one more surprise career twist his sleeve.
The hard-working striker has proven himself as a ruthless finisher in the Premier League, and scored 26 goals in his side's 2015/16 Premier League winning season. Vardy famously turned down a move to Arsenal last summer, but a move to Chelsea could prove too tempting an option for the England international.
The understudy to Danny Rose, Bertrand represents a more realistic and cost-effective alternative to the Spurs star. A former Chelsea youth prospect, Bertrand could jump at the chance to return Stamford Bridge and prove his naysayers wrong.
Since his move to the Saints in 2015, Bertrand has benefitted greatly from the stability gained from regular first-team football with the club.
The 27-year-old has also looked comfortable on the international stage, and would no doubt flourish under the pressures of Champions League football - indeed, the player started in Chelsea's historic Champions League final victory in 2012.
Chelsea are determined to bring in a new wing-back, but Antonio Conte is believed to be confident in his ability to transform Alex Oxlade-Chamberlain into a star in this position.
On paper, the idea works. The 23-year-old still has youth on his side, and possesses both lightning pace and strength. The player is yet to really find a regular position at Arsenal, and under the guidance of Conte he could become a sensation at Stamford Bridge.
The Blues will have to compete with Liverpool for the speedster's signature, but will remain confident of luring the versatile England international to the club.
Chelsea's decision to sell both Nathaniel Chalobah and Nemanja Matić in one transfer window is a move that will continue to perplex and confound the world's finest minds for years to come.
The Blues have set their sights on Danny Drinkwater to fill the gaping hole in their central midfield, and the ex-Manchester United man is more than prepared to make the step-up.
The 27-year-old boasts the attribute that consistently evades English midfielders - being comfortable in possession of the ball, and could work wonders if paired with former fellow Foxes' Premier League winning teammate N'Golo Kanté.
