Eden is looking forward to the day they walk out onto the same pitch together for club or country.
"Despite both of us having been at Tubize, we have never played in the same team," he told the club's official website. "So I hope I can play soon alongside my brother in the national team and also for Chelsea.
"My brother is not the same as me because he is not someone who dribbles a lot. He is more someone who has a passing game in midfield.
"He can play on the wings also but his best position is in central midfield, a number 10."
