In February 2020, Andersson signed for Chelsea, having been recruited from IFK Gothenburg.
The attacking winger has a contract until 2023, but is leaving Chelsea. The 18-year-old confirms the news on Instagram.
“After two years my time at Chelsea is over. I want to thank all the players and staff for making this time very special and helping me develop as a player," he writes.
"Now it's time for a new chapter... Thank you."
