The game creator has signed terms with the Blues, estimated at around 7.1 million pounds a year on a five-year contract.
Leverkusen is already resigned to his star man.
And Bild journalist Christian Falk says the 21-year-old will make it clear that he will move to London as the two clubs continue to haggle over the award.
He wrote on Twitter: “When education resumes at Bayer Leverkusen on Thursday, Havertz to communicate with his club.
“Your request: the bosses let him through to Chelsea.”
Havertz still has a contract until the summer of 2022 and Leverkusen around 90 million pounds for him.
Having signed forward Timo Werner and Hakim Ziyech, Chelsea is reluctant to ask the price.
But Bayer is satisfied with the payments, which can allow Lampard to raise cash by eliminating his first team.
Michy Batshuayi, Marcos Alonso, Danny Drinkwater, Tiemoue Bakayoko, Kenedy and Emerson Palmieri can head to the exit gate.
Leverkusen’s sporting director, Rudi Voller, insisted that the player can leave if a club responds to his requests.
He told Bild, “We have a — if it suits you, you can leave this summer.
“From now on, he’s one of our players. We have our ideas, we know what he can do.
“I hope there’s another year. Of course, you can’t force anyone.
Havertz what he owes to his teammates, to fans and to the club.”
