Lazio and Roma are expected to play out another chaotic Rome Derby on Sunday afternoon (1700 GMT) and football tipster Sergiu Baltuta expects their top scorers to strike.
Before returning to Inter Milan, his second spell at the club, the well-travelled Lukaku also played for Anderlecht, West Bromwich Albion, Everton and Manchester United.
In August 2023, Lukaku joined Roma on a season-long loan from Chelsea, ending the long-running stand-off between player and club.
Lukaku reportedly earned the nickname 'Rocky' while at Manchester United due to his commitment in training. He is a powerful striker and among the most prolific goalscorers in world soccer.
Premier League journeys
Lukaku was handed a chance by the newly reappointed Chelsea manager Mourinho at the start of the 2013/14 season, but the young striker failed to convert a crucial penalty for the Blues in their penalty shootout defeat to Bayern Munich in the UEFA Super Cup. Lukaku was subsequently sent out on loan to Everton.
He joined Everton permanently for a club record £28million in 2014, as Chelsea signed Diego Costa ahead of the new season rather than recall Lukaku.
Old Trafford troubles
Lukaku joined Manchester United from Everton for a reported £75million plus £15million in add-ons in July 2017. Reportedly Lukaku's former club, Chelsea, made a bid for the striker, but he chose Old Trafford over a return to Stamford Bridge.
Lukaku's move to United came despite being managed by Jose Mourinho, who had allowed the striker to leave Chelsea for Everton during his second stint at Stamford Bridge.
After a poor start to 2018/19, Mourinho was sacked in December and Ole Gunnar Solskjaer became the new Manchester United manager. Lukaku did not flourish under Solskjaer and was sold to Inter Milan at the end of the season.
Move to Milan
Lukaku joined Inter Milan in August 2019 for €80million, breaking the club's transfer record. Lukaku struck up a solid partnership with Lautaro Martinez during the 2019/20 season as Inter challenged for the Serie A title.
Moving back to Chelsea
On August 12, 2021, Chelsea re-signed Lukaku from Inter Milan in a £97.5million five-year deal. He had left the Blues to join Everton in 2014, costing the Toffees £28million.
The move meant that more money has been spent on Lukaku than on any other player, having drawn combined transfer fees of £290million.
He scored just eight Premier League goals in 26 appearances, which wasn't helped by a public falling out with Chelsea manager Thomas Tuchel.
In June 2022, Inter Milan secured the services of the 29-year-old Lukaku on a season-long loan, which included a loan fee believed to be around £6.9m.
Lukaku helped Inter reach the Champions League final and win the Coppa Italia, scoring 14 goals across all competitions in the 2022/23 season.
Inter Milan were keen to re-sign him the summer but he was reportedly unhappy after being left out of Simone Inzaghi’s starting line-up for the final against Manchester City in Istanbul, which Inter lost 1-0 after Lukaku came on and missed a late opportunity to level the game.
Moving to AS Roma
At the end of August 2023, Lukaku joined Roma on a season-long loan from Chelsea, ending the long-running stand-off between player and club.
The Serie A club will pay an £8million fee with no obligation to buy while also taking on the Belgium striker’s wages, which will be reduced from the £325,000-a-week he earned at Stamford Bridge.
He will link up with manager Jose Mourinho, with whom he worked during his time at Manchester United.
Lukaku broke into the Belgian national team during their golden era, playing alongside the likes of Eden Hazard, Kevin De Bruyne, Vincent Kompany and Thibaut Courtois, in a team which has consistently led the FIFA World Rankings.
He was once again a key part of the Belgium team for Euro 2020, and he scored four goals in four games before being named in the official UEFA team of the tournament.
Lukaku's father, Roger, played for the Zaire [Democratic Republic of the Congo] national team. His brother, Jordan Lukaku, who made his name as a left-back for Lazio, is currently on loan at Belgian club Antwerp.
Lukaku's Chelsea salary reportedly earns him £15.6m per year, just over £300,000 a week. His total net worth is believed to be around $20m.
Lukaku's sponsorship deals
In 2018, he signed a record sponsorship deal with Puma, but this relationship only lasted two years and he switched to Nike.
Lukaku was the first Premier League player to join Jay-Z's management agency Roc Nation.
