Celtic boss Tony Mowbray played down the spat between Artur Boruc and skipper Gary Caldwell during Sunday's last-gasp 2-1 win over Hearts at Parkhead.
With the Hoops 1-0 down, the excitable Poland goalkeeper parried Andrew Driver's shot and Caldwell raced back to clear the ball off the line - but both players squared up to each other in apparent rage and for a moment the situation threatened to get out of hand.
"If the supporters see players arguing with each other I would suggest it is because they are passionate about the game," Mowbray said.
"Certain fans in Tel Aviv didn't think there was enough passion shown, so you can't then complain if footballers are demanding of each other.
"They walked through the door of the dressing room, shook hands and patted each other on the back.
"It is the emotion of football, it is emotion like the fans get emotional and for me it is a positive."
For the second successive week Celtic had to fight back after conceding an early goal in front of their home fans, a situation which Mowbray admits he will have to address.
He said: "It is an obvious concern that we lose a goal after five minutes and we have to chase the game.
"We are all disappointed with that aspect because we talked long and hard about concentration levels in these sort of games.
"But in saying that, Hearts will take points off other teams."
