Coach Ronald Koeman comes under increasing pressure at the Spanish football club FC Barcelona.
Due to the disappointing zero number at FC Cadiz, the gap between the Catalans in the table on leaders and arch-rivals Real Madrid has already increased to seven points.
Barcelona are in seventh place, but have played one game less.
Even before the yellow-red card for Frenkie de Jong in the 65th minute, the Catalans could not live up to their role as favorites on Thursday evening.
In the closing stages, national goalkeeper Marc-André ter Stegen prevented a goal with a good save and secured at least one point.
Memphis Depay had a great chance to score the winning goal for the Catalans in stoppage time.
The goalless draw was the third competitive game in a row without a win.
The criticism of Koeman had already grown louder after Barca 3-0 at the Champions League opener the previous week against the German champions Bayern Munich.
Most recently, the Dutch coach made a bizarre appearance at a press conference to encourage patience to rebuild his team after the farewell to superstar Lionel Messi.
Nevertheless, speculation about his successor is already circulating in the Spanish media.
Former national coach Joachim Löw is said to be one of the candidates.
