Currently on-loan at Birmingham City, Boga began his football at ASPPT Marseille before his family moved to London.
On the prospect of playing for Olympique Marseille, Boga said: "I followed their start to the season, it is true that it is a new project with OM, but here I do not worry for them, we must give them time and I think they can go make a very good season.
"Every project needs time, it is not in one season that we can be champion or that everything is realized, so I think that with time it will go better and better."
He also told Ultimo Diez: "Yes, I will always be a supporter of OM, that's for sure ... And why not play for OM if the opportunity presents itself? It is a kid's dream as I was born in Marseille."
