Portuguese coach Jorge Jesus was appointed on Tuesday by Al Nassr, where he will link up with Cristiano Ronaldo who signed a new two-year deal with the Saudi club last month.
"It's official: Mr. Jorge Jesus is the new Head Coach of Al Nassr," the club wrote on X.
The 70-year-old Jesus was sacked by Saudi rivals Al Hilal in May following their Asian Champions League semi-final exit.
Jesus was in charge since 2023 in what his second spell with Al Hilal was.
A long managerial career has taken in his native Portugal, notably with Benfica and Sporting Lisbon, and he has also coached in Brazil and Turkey.
Ronaldo, 40, inked a new contract until 2027 with Al Nassr in June, ending speculation over a potential departure.
Although Ronaldo was the Pro League's top scorer with 25 goals last season, he has been unable to win a Saudi or continental trophy with Al Nassr, who also lost in the Asian Champions League semifinals.
