Morocco and Croatia finished 0-0 at the Al Bayt Stadium after an intense opening Group F game yielding a few goalscoring opportunities for both teams.
The last World cup runner-up failed to score for the first time in 16 years with their last goalless draw against Japan in 2006.
Croatia threatened to break the deadlock in the closing minutes when Nikola Vlasic's effort was saved by the legs of Morocco goalkeeper Yassine Bounou and Luka Modric blasted over.
There wasn't much to split the two sides with both of them having just two shots on target in the entire game.
Croatia were most dangerous in the first half with chances -- Luka Modric and Ivan Perisic firing at the keeper but it was Vlasic who really forced a save out of Yassine Bounou.
After the break, Mazraoui saved a diving header while Livakovic denied Hakimi Achraf's long-range strike.
The match ended goalless, the third goalless match in this tournament.
