Chelsea will include the option of a further year in said contract, potentially keeping him at the club until the summer of 2031.
Madueke has flown to London to undergo a medical ahead of signing the contract and completing the move. An official announcement is expected from the Blues later today.
Chelsea’s spending since the Todd Boehly-Clearlake Capital takeover is now close to £450m, with that figure expected to surpass £500m if and when Chelsea sign a new central midfielder.
The west Londoners are interested in Moises Caicedo but Brighton do not want to sell mid-season, especially after they have already lost Leandro Trossard to Arsenal.
101 previously spoke to former Chelsea, Liverpool and Middlesbrough midfielder Boudewijn Zenden about Madueke.
After hanging up his boots, Zenden has spent the last several years working with PSV in some capacity, where he has been able to get an up-close look at Madueke: “He [Madueke] can be dangerous from the right and the middle. In the near future he should be able to play from the left to.
“He has a strong character and believes in himself. His desire to succeed should be a trigger to keep developing as a player.
“His pace is hard to train so he should use it to his advantage. He is always trying to find a way to the goal. That is his best attribute.”
