“Today, I close a chapter that has forever marked my life,” Oscar wrote. “After eight years wearing this jersey with so much pride, it’s impossible not to feel a mix of emotions as I say goodbye.

“These were intense years, filled with hard work, dedication, and, above all, victories. Together, we won everything possible, and this was only achieved thanks to the unconditional support of everyone who is part of this club and its fans.

“I want to thank the club for believing in me from day one. The trust, the support, and the conditions you always provided were fundamental for my growth as a player and as a person.

“To every staff member, coach, teammate, and everyone working behind the scenes – my sincere thanks to you. You are all part of this winning story.”

Oscar moved to Shanghai in June 2017 from Chelsea, where he had won the Premier League title in 2015 and 2017, in a deal that made waves around the football world.

He quickly became a fan favourite and won his first Chinese Super League title in 2018 under Vitor Pereira. He was also instrumental in Shanghai Port’s successes in the 2023 and 2024.

The move to Sao Paulo at the end of his contract sees Oscar return to the club where he started his career having joined the team at youth level before playing there for two seasons from 2008 ahead of a switch to Internacional in 2010.

He moved to Chelsea two years later and made a major impact at the London club before switching to Shanghai.

“How can I describe what you mean to me?” Oscar wrote in an address to the Shanghai Port fans. “You were our fuel through every moment. In victory, you celebrated with us. In tough times, you lifted us up.

“Playing here was a privilege, and feeling your energy in every match is something I will never forget. I take with me incredible memories and the certainty that I gave my all for this club.

“I leave with a heart full of gratitude and pride for everything we achieved together. This club will always be my home, and this fanbase, my family. Thank you for these unforgettable eight years. Thank you for everything.”
