He has made a blistering start to his Manchester United career, and this weekend Romelu Lukaku faces his stiffest test since making the move up the M62.
United travel to Anfield to face their old rivals Liverpool as the international break finally comes to an end.
Lukaku's potential £90m deal already looks like one of the best of the summer, particularly after Kylian Mbappé, Neymar and Ousmane Dembele's money-spinning transfers.
The Belgian forward has 11 goals in his first 10 appearances for Jose Mourinho's side, only failing to score against Leicester City, although he did miss a penalty in that game.
He equalled Andrew Cole's record of seven goals in his first seven Premier League outings for United, a run which included a goal against his former employers Everton.
He has the chance, therefore, to beat that record at Everton's Merseyside rivals on Saturday, and Gary Neville believes this is the type of game that will prove a real test of his qualities.
Neville says that after a string of poor outings against Liverpool, with one goal in his last seven against them, the Belgian must put in a strong performance and prove himself as a match-winner.
“Romelu Lukaku has settled in brilliantly and done everything he was asked to do in terms of converting those home draws into wins, but games like this one are the real test,” the United legend told Sky Sports, as per the Mirror.
“When I look back to the Everton striker’s recent performances at Anfield he didn’t play well, so this is the next step up for him.
“Going away to Anfield is a big test and his service will be more limited so he’s now got to show the ruthless streak to win the big games for United.
“He will be defined by his performances in big matches. You’re at a club with aspirations of winning things and a world class striker will be defined by trophies and performances in big
The former United and England full-back Neville is expecting another rigid display from Mourinho's men in what is a huge game, even after their thrilling start to the season.
They are joint-top with Manchester City, with six wins from their first seven, with four 4-0 wins in that time against West Ham, Swansea, Everton and Crystal Palace.
Mourinho was criticised for his negative tactics when he visited Anfield a year ago, resulting in a 0-0 draw with very few chances for either side.
However, Neville is convinced Mourinho’s side are much more capable of winning at their bitter rivals this time than last, thanks in the main to their attacking options.
“This time it is Liverpool who need to win this fixture and I would expect a lot more from United in terms of being on the front foot," he added.
“It suits Mourinho in terms of his mentality. What I would expect is similar tactics from last season but with more ambition on the counter-attack.
“Paul Pogba is a big absence with his arrogance on the ball, so they will defend deep and be compact again, but whereas there was a back six at times away at Anfield last season, they can commit more on the break.”
