Brussels - A powerful brace from Romelu Lukaku and a glittering performance from Eden Hazard saw Belgium beat Costa Rica 4-1 in Brussels in their final World Cup warm-up on Monday.

But Belgium fans will have watched in horror as Hazard, showing great form lately, limped off in the 70th minute.
His team-mates later dispelled any fears of lasting damage to the diminutive Chelsea forward.
"I'm not too worried about Eden, he's a tough guy. He gets kicked all the time, but soon gets over it," said Lukaku after the game.
Coach Roberto Martinez's multi-talented Red Devils were just too much for Costa Rica, who opened brightly and even took the lead through Brian Ruiz with a slick finish after some early pressure from the visitors.
But the side that beat Egypt 3-0 last week, with a world-class Hazard pulling the strings, was 2-1 up by half-time thanks to finishes from Dries Mertens and Lukaku.
The giant Manchester United target man got his second with a powerful header after running into space with great speed.
He then set up strike partner Michy Batshuayi for the fourth and the pair did a little dance to celebrate.
Belgium's Group G rivals from the World Cup will have been warned, with unpleasant viewing for England, Panama and Tunisia.
