Kai Havertz will earn £210,000 per week if he completes a move from Chelsea to Arsenal this summer, according to MailSport.
The German forward has agreed on a five-year contract in principle with the Gunners.
All that is left is for the two London clubs to strike a deal on the transfer fee.
Arsenal has made an improved verbal offer worth £60 million for Havertz.
The new package is believed to be worth a guaranteed £55 million plus an extra £5m in bonuses.
Having seen their original offer of around £50 million turned down by Chelsea last week, Arsenal have continued talks with the Blues.
Arsenal wants to wrap a deal up quickly as they already have a broad agreement in place over personal terms.
