Co Adriaanse has resigned as coach of FC Porto on the eve of the season after winning a Portuguese double in 2005/06.
A club statement said: "Jacobus Adriaanse, Porto's head coach, handed in his resignation on Wednesday and has already said goodbye to all the players. He did not lead this morning's training session. He opted not to join the team on their trip to England where Porto will have a number of training sessions and matches."
Ex-Porto player Rui Barros has stepped in as caretaker with the UEFA Champions League group stage contenders expected to announce a permanent successor soon. Former AZ Alkmaar coach Adriaanse, 59, was installed at the Porto helm last May, taking charge on 4 July to replace current Portugal Under-21 chief José Couceiro.
