Chelsea boss Guus Hiddink has played down a training ground bust-up between Oscar and Diego Costa, describing them as "two bulls" squaring up to each other.

Costa reacted to a bad challenge from his team-mate, although Oscar denied a fight had occurred.

Hiddink says Oscar's tackle was part of an intense training session and he is not at all worried about the incident.

Hiddink also confirmed that his second tenure as interim boss definitely will finish at the end of the season, amid claims that he was considering carrying on.
