Pierre-Emerick Aubameyang was assaulted as an armed gang equipped with iron bars targeted his house in Barcelona.
Aubameyang and his wife were handcuffed and tied up for a sustained period during the burglary, although club sources say neither suffered serious injuries.
The house is about 200 metres away from properties still owned by ex-Barca stars Lionel Messi and Luis Suarez, who both use private security firms to safeguard their homes.
The gang forced him to open a safe that contained jewelry, among other expensive items, which they took.
The gang have not yet been caught, according to police sources.
Robert Lewandowski had his watch stolen from his car as he arrived for training last week.
