Oscar & Costa involved in training ground fight

Diego Costa and Oscar had to be separated by team-mates
after a bust-up during a Chelsea training session, according
to The Telegraph.

The incident occurred after a robust challenge by Oscar, with a source quoted as saying: "Oscar's challenge was
outrageous, it was straight into the knee of Costa and could have done him some real damage.

"That sparked a brawl between them and the other players
had to stop it."

The report states the pair settled their differences soon after,
with interim manager Guus Hiddink unconcerned by the
disagreement ahead of the weekend FA Cup tie against
Scunthorpe United.
