Romelu Lukaku's early goal on his 100th cap helped Belgium ease past the Czech Republic 3-0 at the King Baudouin Stadium in Brussels on Sunday evening.
New Chelsea signing Lukaku gave Roberto Martinez' side the lead after just eight minutes, before Eden Hazard doubled the advantage four minutes before half-time, both goals set up by Hans Vanaken.
Substitute Alexis Saelemaekers put the cherry on the cake shortly after coming on, giving Roberto Martinez' side, ranked first in the world, a six-point lead at the top of World Cup qualifying Group E.
