Brazil striker Neymar scored all of Santos's goals in their 4-1 win against Atletico PR in Sao Paolo.
The 19-year-old scored a second-half hat-trick to move his side up into 10th place in La Liga.
Neymar has been repeatedly linked with moves to Spanish giants Barcelona and Real Madrid.
However, he recently revealed that he was happy in Brazil and would not yet be moving to Europe.
