As the first Premier League club to embrace the arrival of a billionaire owner, Chelsea have given Roman Abramovich’s bank account a bit of a battering down the years – but he can afford it and considerable expenditure has delivered tangible reward at home and in Europe. Who, though, are the club’s most elaborate purchases? Goal takes a look at the top 10...
ALVARO MORATA - £70m
Six years after setting their transfer record with Fernando Torres, Chelsea shattered it by bringing Alvaro Morata in from Real Madrid.
The Spain international made a name for himself during a two-year spell at Juventus before Madrid bought him back last season. Morata made the most of his limited action there, scoring 15 La Liga goals in 26 appearances and just 14 starts.
Expected to be given a consistent starting place once more, Morata will aim to continue his ascent at Stamford Bridge.
FERNANDO TORRES - £50m
The Blues smashed the British transfer record to bring a World Cup-winning striker to Stamford Bridge from Premier League rivals Liverpool during a memorable January 2011 transfer window.
Unfortunately, the Spaniard has come to embody the big-money flop moniker and left the club having failed to find his spark and without a double figure goal return in any of his four Premier League campaigns.
TIEMOUE BAKAYOKO - £40m
The Blues made the 22-year-old midfielder their third signing of the summer of 2017 on July 15. The former Monaco player became the second-most expensive Blues player ever, quickly topping the fee Chelsea paid for Antonio Rudiger.
Bakayoko is a tough two-way player and has become a senior international for France, making his debut in March 2017.
ANTONIO RUDIGER - £34m
Used to playing in a back three, he adds depth to Conte's squad in a variety of different roles.
DAVID LUIZ - £34m
They then sold him to Paris Saint-Germain for £50 million in the summer of 2014, only to bring him back for a second spell at Stamford Bridge two years later .
MICHY BATSHUAYI - £33.2m
The form of Diego Costa kept him on the sidelines for much of his debut campaign in 2016-17, but he will forever be remembered for netting the Premier League title-clinching goal in an away date with West Brom .
N’GOLO KANTE - £32m
Having inspired Leicester to a remarkable Premier League title triumph, Chelsea sought to acquire the skill set of a unique talent in the summer of 2016.
The France international picked up with the Blues where he had left off with the Foxes, with his control of midfield seeing him land back-to-back top flight crowns and the PFA Player of the Year award .
DIEGO COSTA - £32m
Two 20-goal hauls have delivered as many Premier League crowns, but the enigmatic frontman appears destined to move on after being informed that he no longer figures in Antonio Conte’s plans .
EDEN HAZARD - £32m
Chelsea’s Champions League triumph in 2012 helped them to win the race for one of the most sought-after talents in European football, with the Belgian playmaker arriving from Lille.
Five seasons in west London have delivered two Premier League titles, a League Cup win and Europa League triumph, with the 2015 PFA Player of the Year providing plenty of memorable moments along the way.
ANDRIY SHEVCHENKO - £30.8m
The 2004 Ballon d’Or winner completed a high-profile but controversial move to Stamford Bridge in 2006, with Abramovich reported to have forced through a deal against the wishes of Jose Mourinho.
The Ukrainian frontman was an iconic figure when he arrived in England, but left three years later having managed just 22 goals in 77 appearances.
