Diego Costa - Spotlight on
Reports emerged yesterday that the two players had clashed during a training session ahead of the Premier League champion's FA Cup clash with Scunthorpe.
But the Dutch manager revealed that no disciplinary action would be taken against either player after they squared up to each other at Chelsea's Cobham training ground.
"They were like bulls who were chesting a bit after a charge from behind by Oscar," said Hiddink.
But Hiddink also revealed that the players were laughing about the incident and that Oscar made a speech at the end of the session.
"Oscar said to me he wanted to say a few words," Hiddink added.
"So I told him to take the podium and he apologised in front of the whole squad."
