Romelu Lukaku celebrated his 100th international with a goal as Belgium opened up a six-point lead after a 3-0 win against the Czech Republic in World Cup qualifying. “The players did exactly what I asked of them,” Belgium coach Roberto Martinez said. “But we need to stay focused for the next game.”

That game is against Belarus on Wednesday, when Wales hosts Estonia. Lukaku scored in the eighth minute at King Baudouin Stadium, his 67th goal for the national team. Eden Hazard doubled the lead shortly before half-time and Alexis Saelemaekers put the result beyond doubt with a goal in the 65th.
