Greek league leader Olympiakos have fired former Portugal coach Paulo Bento as manager after a third straight league defeat.
The club said on Monday that youth coach Vassilis Vouzas has been appointed caretaker coach.
Olympiakos have only lost two league titles since 2000 and currently lead with 51 points from 23 matches.
But their advantage was narrowed further by a 2-0 loss at PAOK on Sunday.
Bento, a former national team defender and coach, took over at Olympiakos in August last year.
