Shanghai SIPG have reportedly submitted an offer to Borussia Dortmund worth €150 million ($157 million) for Pierre-Emerick Aubameyang.
Aubameyang would be paid a salary of €800,000 per week.
Aubameyang is one of Real Madrid's biggest targets for next season.
Shanghai SIPG recently bought Oscar from Chelsea for €61 million.
Dortmund paid just €13 million for Aubameyang in 2013 and he'd now command at least €80 million in the current market.
