Former Chelsea star Oscar has reportedly decided to retire from football after being diagnosed with a medical condition last month.
Oscar was diagnosed with vasovagal syncope following his sudden collapse during a Sao Paulo training session.
The condition can be controlled with medication or a minor procedure to cauterise a node responsible for sudden drops in blood pressure.
Vasovagal syncope is not considered life threatening when managed appropriately.
Brazilian outlet Globo has reported that Oscar has discussed his future with those close to him and Sao Paulo.
The midfielder has reportedly informed the club of his decision to retire, allowing them to plan ahead for next season without him.
