Belgium get off to a stuttering start in Brazil after coming back from a goal down to beat the North Africans 2-1.  Much-fancied Belgium fought back from a goal down to score twice in the final 20 minutes and earn a hard-fought 2-1 victory over gutsy Algeria in their World Cup Group H opener.

Belgium, back at the World Cup after a 12-year absence, enjoyed the majority of possession but struggled to break down a disciplined two-line Algerian defence which kept Eden Hazard and forward Romelu Lukaku well in check.

The Algerians, with El Arabi Soudani surprisingly in the starting lineup for key forward Islam Slimani, posed little threat up front with winger Riyad Mahrez firing well wide in their only foray in the Belgian box early in the game.

Feghouli calmly fired past keeper Thibaut Courtois to end his country's 28-year wait for a World Cup goal and send the green-white-clad Algerian fans delirious.

Belgium's Axel Witsel tried his luck with a couple of long-range shots but the Red Devils looked nothing like the menacing team that qualified unbeaten for the tournament.

Coach Marc Wilmots, the last Belgium player to score in a World Cup, took off lacklustre Lukaku early in the second half, bringing on teenager Divock Origi in the hope of breathing new life into his team.

It was Wilmots' other substitute, Fellaini, who delivered when he rose high to meet a Kevin De Bruyne cross and drill his header off the bar and into goal on 70 minutes.

The Desert Foxes, who had hardly put a foot wrong in defence, were caught napping 10 minutes later when Hazard raced down the left wing, and cut back perfectly for subsititute Mertens to fire in for the win.
