A stunning volley from Dries Mertens and a Romelu Lukaku double broke the resistance of a brave Panama side on their World Cup debut as Belgium cruised to a 3-0 win in their opening Group G game on Monday. Mertens hammered home a superb volley two minutes into the second half, sending the ball arcing over Jaime Penedo after Panama struggled to clear a cross. Lukaku’s hard work up front was rewarded when he headed home Kevin De Bruyne’s brilliant pass off the outside off his foot to make it 2-0 in the 69th minute and the big striker latched on to an Eden Hazard pass to complete the scoring with a neat finish.
