According to MailSport, Kai Havertz would make £210,000 per week if he moves from Chelsea to Arsenal this summer.
The Gunners and the German forward have reached an agreement in principle on a five-year contract.
The transfer fee must yet be agreed upon by the two London clubs.
An enhanced verbal offer from Arsenal for Havertz is around £60 million.
The estimated value of the new package is a guaranteed £55 million plus an additional £5 million in bonuses.
After Chelsea rejected Arsenal’s initial offer of roughly £50 million last week, the two sides are still in contact.
Arsenal wants to close a deal as soon as possible because they have a thorough understanding of the personal details already.
