Diop, born in Toulouse, to a Moroccan mother and a Senegalese father is eligible to represent the reigning world champions and the two African nations at senior level.
The 20-year-old who was part of France's squad that won the Uefa European U19 Championship in 2016, is the grandson of Lybasse Diop - the first Senegalese to play in the French Ligue 1.
And after switching to the English Premier League this summer for a club-record fee, the former Toulouse centre-back is hoping to get a chance in Didier Deschamps' squad in the future.
“It has always been a dream to play for France. If it happens, it happens, otherwise too bad!, " Diop told Ladepeche.
“I have always said that I will only play for France and for no-one else. Whether I'm selected or even if I'm never selected with the seniors, I will not play for another country.
“I was born in France, it's France that I have everything for, so I do not see why I would play for another country."
