Cristiano Ronaldo's Saudi club Al-Nassr announced the departure of Portuguese coach Luis Castro on Tuesday, a day after starting their AFC Champions League Elite campaign with a disappointing draw.
Monday's 1-1 stalemate with Iraq's Al-Shorta in the Asian competition compounded a slow start to the domestic season with the current contract of Ronaldo, 39, due to expire next summer.
"Al-Nassr can announce that head coach Luis Castro has left the club," said a statement posted on X.
"Everyone at Al-Nassr would like to thank Luis and his staff for their dedicated work during the past 14 months, wishing them the best of luck for the future."
Castro, 63, is the third coach to depart Al-Nassr since Ronaldo's groundbreaking arrival in early 2023.
Frenchman Rudi Garcia quickly left that April, followed by a brief stint by Croatian coach Dinko Jelicic before Castro was appointed in July last year.
Al-Nassr, who finished a distant second in the last Saudi Pro League season, have drawn twice in three matches at the start of the new campaign.
