ROSTOV-ON-DON, Russia -- Brazil has spent four years trying to atone for its last World Cup match, the calamitous 7-1 defeat as hosts by Germany. Popular coach Tite purged players, eased dependence on Neymar, and rebuilt a team that concedes few goals and blazed through qualification.

Those changes will be tested Sunday, when the Selecao start their campaign for a sixth World Cup title at the southern Russian city of Rostov-on-Don against Switzerland.

Few embody Brazil's rediscovered spirit more than Gabriel Jesus, the 21-year-old Manchester City striker: Four years ago he was photographed as a barefoot teenager painting the streets of his Sao Paulo neighbourhood. Fast-forward to Russia and he's a valued team resource, the top scorer in qualification with seven goals.
