Midfielder Otavio has left Porto for Saudi club Al-Nassr in a deal worth 60 million euros ($65.1 million), the Portuguese club said on Tuesday.
The Brazilian-born Otavio joined Porto in 2014 from Internacional and made his international debut for Portugal in 2021.
He will link up with Portugal teammate Cristiano Ronaldo at Al-Nassr.
"It's difficult to leave the club after nine years here," the 28-year-old told the Porto website.
