Guus Hiddink laughs off clash between Costa and Oscar
Chelsea interim boss Guus Hiddink suggested Oscar benefits from being antagonised after the Brazil playmaker's training ground confrontation with Diego Costa was laughed off.
Tensions boiled over ahead of tomorrow's FA Cup third-round tie with Scunthorpe after robust tackles were exchanged during training at the Blues' Cobham base.
Costa took exception to a challenge from Oscar, with the swift intervention of team-mates required to help defuse the situation.
The pair later joked about the incident, but Hiddink suggested the slight Oscar benefits from becoming angry.
"When this guy puts the emotion in, his level of play rises. We try to punch him every now and then to get him on this level," he joked.
Hiddink downplayed the scale of the confrontation, which came during an "intense" training session.
"It was a pity that our photographer had a day off because he could've shot beautiful pictures of two bulls who were chesting a bit," said Hiddink, who succeeded Jose Mourinho last month. "He got Diego. Then they stumbled over, stood up as a normal reaction and then chested a bit.
"Oscar apologised in front of the group. They looked at each other and then they started laughing. Jokes were made afterwards."
Chelsea have only one fit striker in Costa, with Radamel Falcao (groin) and Loic Remy (calf) absent.
Hiddink did not directly respond to speculation about Falcao's loan from Monaco being cut short, only considering the Colombian's fitness.
"I'm worried about his situation," Hiddink said.
