Chelsea striker Romelu Lukaku feels there's more to come from him in the World Cup.
Lukaku was quiet in Belgium's win over Algeria.
"It was good," he said. "The most important thing was to win and it is good for the confidence. I scored a goal and our bench made the difference; we had a big impact.
"It was a great goal, it was great for me and for the team. It's not been the best season for me but football is like this.
"It is a boost for the confidence of the Belgian team. Algeria made it so tough, but we showed our character and ability."
