Bobo got the only goal as Sydney FC ended a derby drought in their rivalry with Western Sydney Wanderers, whose hopes of reaching the A-League Finals suffered a major blow.
The 1-0 win for Sydney FC at the SCG extended their 100 per cent record – now three wins from three – in games played at the world-famous cricket ground.
Brazilian Bobo and Western Sydney's Bruce Kamau had goals disallowed before the game's decisive moment arrived in the 62nd minute, Milos Ninkovic's dinked cross from the left deftly headed into the bottom right corner by Sydney's prolific striker.
It gave Bobo a 10th goal in 19 A-League appearances this season and his fifth goal in games between the Sky Blues and Western Sydney. Only Alex Brosque (six) has scored more goals in the history of the rivalry.
The neat finish also allowed Sydney to end their six-game winless run against Western Sydney (L3 D3), with their most recent previous victory having come in December 2018.
Sydney sit second in the table, with Melbourne City having already secured the Premiers Plate, but the race is on for post-season places and Western Sydney are in danger of missing out. Needing a top-six finish, they sit ninth with three games remaining, three points adrift of sixth-placed Brisbane Roar, who have a game in hand.

Adelaide United nudged up to third position with a 1-0 win over lowly Melbourne Victory, with Craig Goodwin scoring in the 39th minute, securing a seventh win for the Reds in the last eight league meetings between the sides.
Perth Glory's Finals hopes were hit by a 1-1 draw against fifth-placed Macarthur.
Diego Castro put hosts Perth ahead in the 13th minute from the penalty spot after Andy Keogh was impeded, but Matt Derbyshire levelled on the half-hour mark, plundering his 14th goal of the campaign from close range.
