With everything that has happened recently, everyone in France was affected, so we will see what happens in the quarter-finals, said Crystal Palace striker Mateta after wearing the captains armband and scoring the opening goal in Tuesdays 3-0 win against New Zealand in Marseille.
A third win out of three in the first round, each one with a clean sheet, allowed the Thierry Henry-coached hosts to finish on top of Group A.
That set up a last-eight tie against Argentina, who qualified for the knockout phase earlier Tuesday by beating Ukraine 2-0 in Lyon but missed out on first place in Group B as Morocco pipped them on head to head.
The tie, which will be played on Friday in Bordeaux, will be the first meeting of the nations since Argentina players were recorded singing racist chants about their French counterparts as they celebrated winning the Copa America earlier this month.
FIFA said it would investigate the chants, which targeted Frances star striker Kylian Mbappe among others and included racist and homophobic insults.
