Chelsea interim manager Guus Hiddink has played down reports of a spat between Chelsea striker Diego Costa and midfielder Oscar.
Reports claimed that the two were separated by team-mates after the Brazilian tackled the Spaniard in training.
But the Dutchman says Oscar apologised to his team-mate and the two joked after the incident.
"There would have been some beautiful pictures of the two bulls who were chesting a bit after a challenge from behind from the smallest bull - Oscar," Hiddink explained.
"His challenge from behind was overdone, especially when you know Oscar who is not the biggest tackler in the team. They stumbled over, stood up and chested a bit without any further seriousness.
"It was the threat of two bulls. We came in between but there was no need to grab them to avoid them hitting [each other]. It was an intense and sharp training session and these things happen.
"After that Oscar apologised in front of the group for his overreacting and they looked at each other and started laughing.
"Jokes were made after. It's solved."
