"In the end, I think we got what we deserved," the midfielder told FIFA.com. "We started very nervously and played badly in the first half, but I think you saw the character of this team in the second half.
"We just needed to stay calm, make the right decisions, and doing that got us this fantastic result.
"I'm really happy, both for myself and for the team. Scoring at a World Cup was a great moment for me and I immediately thought about my family, who always supported me through the years no matter what. Everything they did for me led to that moment."
Belgium are back in action on Sunday when they meet Russia in Rio de Janeiro.
