Ayari, who recently turned 23, scored the 3-0 goal at home against Crystal Palace in the tenth minute, putting Brighton on the scoresheet.
He also scored earlier in the season in the 5-0 away win against Coventry.
In a recent Nations League game, Ayari scored one of the goals in the 2-1 home win against Poland - and at this summer's World Cup, he scored twice in the 5-1 thrashing of Tunisia.
