United announced on Saturday morning they had agreed what is thought to be a world record fee for the Belgian striker and he is all set to have a medical in Los Angeles and join up with the Reds for their pre-season tour.
All summer before this weekend, Lukaku was destined for a return to Stamford Bridge and play for the reigning Premier League champions but it all went wrong very quickly indeed.
How did the Blues allow this to happen?
Antonio Conte will be absolutely fuming. Chelsea fans will no doubt be frustrated, even despite the eye-watering price tag slapped on their former strikers head, but by all accounts, Lukaku was going to be back in west London for the start of the new season.
By the looks of it, Chelsea have been well and truly done like a kipper by their former manager, Jose Mourinho.
Around a year ago, it emerged that Chelsea didn’t have a buy-back clause inserted into Lukaku’s contract when he left the capital and joined Everton and it was Mourinho has said no to it.
Everton signed Lukaku for £28m in 2014 after a loan spell, but without that clause, Chelsea wouldn’t have first refusal if he set the Premier League alight – which he did.
According to sources close to that deal, Chelsea were thinking of accepting a lower fee from the Merseysiders but with a buy-back option in the contract. Lukaku was keen, Mourinho was not.
Chelsea have wanted their former employee for the past two years. Last summer, they baulked at the £60m price tag. Then, he went on to score £26m and is no going to cost Man Utd £100m.
While Mourinho is gone from Stamford Bridge, his impact is still reigning over west London but this time, it’s not in a good way.
