Romelu Lukaku makes his a double as Belgium power to an 8-1 rout against Estonia
Romelu Lukaku helped give his former Everton boss Roberto Martinez a night to remember as Belgium hit eight against Estonia in their World Cup qualifier in Brussels.
The Red Devils had won their first three qualification games under Martinez and they impressed once more as they ran out comfortable 8-1 victors.
Thomas Meunier headed the hosts ahead before Dries Mertens and Chelsea forward Eden Hazard struck. Henri Anier pulled one back for Estonia, but Belgium ramped things up. Yannick Carrasco converted Lukaku's cross before Ragnar Klavan scored an unfortunate own goal.
Mertens added his second before Toffees striker Lukaku added the seventh and eighth.
Belgium are now clear at the top of Group H, with Greece in second spot following Giorgos Tzavelas' injury-time equaliser at home to Bosnia-Herzegovina.
The visitors looked set to hang on to the lead given to them by goalkeeper Orestis Karnezis' first-half own goal, but Tzavelas lashed home with seconds left.
Cyprus, meanwhile, beat Gibraltar 3-1.
In Group B, Portugal won 4-1 against Latvia, skipper Cristiano Ronaldo scoring twice and also missing a penalty.
The Real Madrid forward netted a penalty after Gints Freimanis had fouled Nani. But, after Glebs Kluskins felled Andre Gomes on the hour, Ronaldo scuffed his second spot-kick.
Arturs Zjuzins levelled, but Latvia's hope was short-lived as William Carvalho's header had Portugal back in front. Ronaldo atoned for his miss by volleying in a third before Bruno Alves wrapped up the win.
Switzerland recorded a 2-0 win over the Faroe Islands and Hungary eased to a 4-0 success over Andorra.
In Group A, Memphis Depay scored a brace in Holland's 3-1 win against Luxembourg.
Bulgaria are just a point adrift after a 1-0 win over 10-man Belarus in Sofia.
