As he prepares to return to Chelsea in a £98 million move, Belgium's Romelu Lukaku is likely to surpass Neymar as the most expensive player of all time.
After a three-year spell at Stamford Bridge, he left in 2014.
The Belgian has 177 goals in all competitions since joining Inter Milan from Manchester United, with 30 of them coming last season when the Italian club won their first Serie A title in 11 years under Antonio Conte.
Lukaku is ready to join Chelsea after the club agreed to pay Inter Milan £97.5 million, a club-record fee for the reigning European champions.
Lukaku's career transfer fees will total £293.5 million, surpassing Neymar's record of £246.6 million set when he left Barcelona for PSG.
Cristiano Ronaldo is third in the all-time list of transfer fees, having moved from Sporting Lisbon to Manchester United for £12 million in 2003, United to Real Madrid for a then-world record fee of £80 million in 2009, and most recently from Real to Juventus for £100 million in 2018, bringing his total to £192 million.
Eden Hazard is in fourth position, having moved from Lille to Chelsea for £32 million in 2012. The Belgian was one of the world's hottest young talents at the time.
