A first-half goal from Daniel Alves gave Sao Paulo a winning start to their 2020 league season on Thursday as the home side overcame Fortaleza 1-0 at the Morumbi stadium.
The former Barcelona player stole in at the back post to side foot home a cross two minutes before the break.
Sao Paulo's first game of the season was postponed just minutes before kick-off on Sunday when members of the opposing team tested positive for COIVD-19 so Thursday's win signalled their first points of the campaign.
The result condemned Fortaleza to a second straight defeat after a 2-0 loss at home to Athletico Paranaense at the weekend.
Sao Paulo's next match is away at Vasco on Sunday, while Fortaleza are at home to Botafogo the same day.
