Orlando City's Kaka made his second debut for Sao Paulo on Sunday night, scoring in a 2-1 defeat away to Goias.
The star-studded Soberano were the Brazilian midfielder's first club, and he is now back on loan at Estadio do Morumbi from Major League Soccer's latest franchise.
Lining up alongside international teammate Ganso, the 32-year-old was heavily involved in the visitors' attacking plays in the first half, but they fell behind just before the interval, with Amaral planting a bullet header into the top corner.
Incredibly, the deficit was soon doubled. Alexandre Pato entered the fray for the three-time South American champions at the break, but Bruno Mineiro promptly nodded a second past Rogerio Ceni from close range.
With the Esmeraldino now desperately defending, Kaka's big moment finally came in the 76th minute. A ricochet in the area fell at the Gamense's feet, and he coolly slotted beyond Renan into the net.
However, despite late pressure, Goias were able to hold on for their first win in five.
Sao Paulo had been seventh in Brazil's Serie A at kick-off, and lay a huge nine points behind a rampant Cruzeiro side, having lost at home to minnows Chapecoense in their previous match.
Their last trophy was the Copa Sudamericana in 2012, and they haven't won the national league title in six years.
Kaka made 125 appearances for the Tricolor between 2001 and 2003, scoring 47 goals, earning himself a big move to AC Milan. Two spells in Italy were separated by a stint at Real Madrid - his time in Europe bringing eight major honours and one FIFA World Player of the Year award.
He will rejoin Orlando as their first Designated Player at the turn of the year, in time for their maiden MLS campaign.
Meanwhile, City are cruising to the title in the USL Professional Divison, but lost for the first time in 2014 at the hands of the Rochester Rhinos.
The Lions sloppily lost the ball in midfield in the 30th minute, and Chris Rolfe capitalised to curl the New Yorkers ahead, after playing a one-two with strike-partner Levi Houapeu.
That proved to be the only goal of a game where Tyler Turner, Tommy Redding, Darwin Ceren and Kevin Molino all featured, though future MLS colleague Yordany Alvarez was not involved.
