Boosted by Neymar's first start since his foot injury in February, Brazil went on the charge against Austria and finally broke the deadlock in the 36th minute.
Marcelo picked up the ball in midfield before trying an ambitious shot from range which slammed into one of his team-mates.
Fortunately for the 'Selecao', the rebound landed at the feet of Jesus who was out on the left of the box.
The Manchester City striker controlled the loose ball well before moving onto his right foot to curl and stunning shot out of the reach of opposing goalkeeper Heinz Lindner and in off the far post.
However, replays showed that Jesus was just in an offside position when the ball deflected off his team-mate and that the official probably would have seen it if he wasn't obstructed by Willian out on the right wing.
Nevertheless, the goal stood and Brazil went into half-time with a 1-0 lead and it meant Jesus' international numbers continued to impress, netting 10 times in 16 games.
