Doucoure played with Manchester United ace Paul Pogba with France's youth teams.
He watched on TV as Pogba and another former team-mate from the U17s, Samuel Umtiti, lifted the World Cup.
Did he have mixed feelings, wondering what could have been?
“Of course I'd love to play with Paul again one day in the midfield. Why not?
“I'm only 25. I have time to play a World Cup, a European Championship. It's my dream. Now I want to get everything I didn't have in the past."
