DIEGO Costa and Oscar have been involved in a training ground fight lasting over two days.
The Chelsea players have been desperately trying to land a blow on each other in a bid to end the fight, but have so far been unable to find their target.
Coach Roy Hobbs said: “Occasionally they’ll fall to the ground clutching their faces and roll around for a bit.
“I even tried to show them where they were going wrong by repeatedly belting John Terry in the mouth. I kept going for half an hour before anyone said anything.
“Anyway, they’re still out there, feebly wafting their fists at each other.”
Manager Guus Hiddink tried to play down the situation by claiming they were both trying to shoo away a wasp.
Hobbs added: “We might put one of them out on loan to end the fight as it’ll make it a nice, even 100 players we currently aren’t using.”
