West Ham United's recent run of form, with four points from their last two matches, will be tested when they face their nemesis on Saturday.
In his last nine Premier League meetings with them he has plundered nine goals for Everton and Manchester United.
He only failed to register in one of those league matches, for Everton in April 2017, but made up for it with two goals in his most recent match, Man Utd's 4-0 win in August last year.
Manuel Pellegrini's side have home advantage but it appears that playing on the road suits Lukaku more.
All the Belgian's four Premier League goals this season have been scored away from home.
A strike at the London Stadium would make Lukaku only the fourth player to score in his side’s first four away fixtures in a PL campaign.
