The Liverpool striker was on fine form for his country earlier on Thursday.
Firmino was one of three Liverpool players who travelled to Singapore for the fixture, with Fabinho named on the bench for the Brazilians and Sadio Mane playing for their opposition.
The Reds forward didn't waste much time in getting himself on the scoresheet, chipping a delightful opener into the net after just nine minutes.
He's been in electric form of late, creating three assists and scoring another for Liverpool in the English Premier League and UEFA Champions League since the last international break.
That he is continuing with that kind of momentum is a great sign for Liverpool that he won't dip in form.
Jurgen Klopp's side have a massive schedule of fixtures on the horizon, starting with a trip to Old Trafford to face Manchester United.
They haven't won at the venue since 2014 but will be hoping to pick up maximum points and maintain their eight point lead at the top of the league table.
With matches against Spurs and Arsenal to follow, as well as European action, this is a critical time for Firmino and his teammates.
These fans were excited by his contribution today, taking to Twitter to share their thoughts after his international goal...
