Neymar scored twice for Santos and responded to his critics with a tongue-in-cheek goal celebration on his return to action after Brazil's disappointing World Cup campaign.

Neymar responded by celebrating his opening goal with a card-dealing gesture before using a corner flag to mimic a golf swing.
