CELTIC manager Ronny Deila claims dressing room harmony is not a concern despite an internal bust-up between two players on the training ground on Tuesday.
Emilio Izaguirre required stitches in his ear after summer signing Nadir Ciftci lashed out at the defender following a tackle he took exception to.
Deila was not present when the incident occurred, but revealed he is aware of what happened and has already brushed it under the carpet.
"It happens all the time," he said in Tuesday’s press conference ahead of Wednesday’s meeting with Hearts.
"We want intensity in training. It was a tackle and a reaction and he [Izaguirre] got hit in his ear. He had to go to get it stitched and he's fine for tomorrow [Wednesday].
"It was a reaction from another player to a tackle. I always say to my players I want 100 per cent. They are very good at that.
"I wasn't there. We sorted it inside. We talked with both of the players and we are finished with it and we move on."
Last Thursday, playmaker Kris Commons reacted furiously towards the coach’s bench after being substituted during Celtic’s 3-1 defeat to Molde in the Europa League, but Deila insists the mood in the camp is as positive as ever.
He added: “We have a fantastic atmosphere in the training pitch. It's been very good lately. Sometimes it goes a little too hot and today there was an incident but I have talked with both players and everybody is ready [for Hearts]."
