Matheus Cunha scored twice as Brazil moved top of World Cup Group C with a 3-0 win over Haiti. Vinícius Júnior netted the third, with all of the goals coming in a first half during which Brazil looked markedly improved from their insipid opening draw against Morocco.

The result means Haiti, who lost to Scotland 1-0 in their first game, can no longer reach the knockout phase.

Brazil ran riot in the first half, helped by some generous defending from the Caribbean side, whose high line gave Cunha, Raphinha and Vinícius plenty of opportunities to run in behind.

Raphinha had a 12th-minute strike disallowed for offside. The Barcelona forward latched on to Bruno Guimarães’s through-ball before finishing well, only for the assistant’s flag to correctly signal he had moved a fraction early.

Ten minutes later Raphinha was sent clear again, but the former Leeds player lifted his finish wide of the target, with the offside flag once more raised.

A minute later Brazil went ahead through Cunha. Vinícius cut in from the left and his curling effort was parried by Haiti goalkeeper Johny Placide to leave the Manchester United forward with a simple finish.

Cunha scored his second after 36 minutes as Haiti lost the ball in midfield, Vinícius played the former Wolves man in on the left and he smashed a first-time finish into the roof of the net.

An excellent start for the five-time winners was tarnished somewhat as Raphinha went off before half-time with what looked to be a hamstring injury, with Bournemouth teenager Rayan replacing him.

Vinícius went from provider to scorer in first-half stoppage time as the Real Madrid forward latched on to Lucas Paquetá’s lofted pass and slotted the ball past the helpless Placide.

Haiti produced their first shot of the game after 48 minutes as Danilo gave the ball away cheaply and Sunderland’s Wilson Isidor – on as one of two half-time substitutes – hit a tame effort at Alisson.

Alisson denied Haiti their first World Cup goal since 1974 with a point-blank save as Ricardo Adé headed a corner goalwards.

Jean-Kévin Duverne prodded an effort wide for Haiti, while at the other end substitute Gabriel Martinelli saw an effort tipped against the crossbar by Placide.

Douglas Santos fired over, Endrick had an effort ruled out for offside and Ederson put a good chance wide but Brazil were unable to add to their tally in the second half.

Isidor drew an excellent save from Allison and Dominique Simon’s stoppage-time effort from distance was also kept out by the Liverpool goalkeeper as Haiti became the first side to be eliminated from this year’s tournament.
