Andre Ayew equalised for the Black Stars, but Joao Felix and Rafael Leao scored their first World Cup goals to put Portugal 3-1 up.
Osman Bukari made it a tense finish with a close-range header and Diogo Costa almost handed Inaki Williams a stoppage-time equaliser only for the forward to slip at the vital moment.
Brazil and Serbia faced off in their 2022 FIFA World Cup opener with solid performances on both defensive ends.
Brazil dominated in knocking shots off on goal, and despite their close attempts, were unable to find the net.
The match stood 0-0 at halftime.
The game took a quick tu after Brazil found their stride late in the second half and Richarlison went on to score his long-awaited first goal in the 62nd minute. Twelve minutes later, Richarlison went on to strike again with an impeccable scissor kick from the center of the box to hold the lead over Serbia.
A beautiful 2-0 finish over Serbia for Brazil: a win to remain unbeaten in their last TWENTY World Cup opening games.
