The Belgium captain is under pressure after last week's friendly defeat to Spain.
"By nature I am not a leader, but I do try to be one," he conceded. "I'm not the only leader of this team: There are a lot of players with a lot of experience."
On last week's game, he added: "Being booed is never fun, but we are professionals and accept it.
"However, we must not forget that Spain is one of the best teams in the world."
