Sosa, who is 25 years old, had previously joined Nottingham Forest from CA Talleres in Argentina just a year ago. During his time with the English club, he made 23 appearances and scored three goals, although he started only one Premier League match.
Now, Sosa has returned to South America to take up a new challenge with Palmeiras, a move that is expected to bring new opportunities and experiences for the young player.
It is worth noting that Sosa's move to Palmeiras marks a significant change in his football career, and it will be interesting to see how he adapts to his new team and the Brazilian football scene.
