Newcastle boss Alan Pardew is determined to keep a cool head in ahead of the north-east derby with Sunderland.
He said: "There is a little bit of passion flying about and it needs to be conducted in the right manner by players and staff alike.
"But emotions sometimes get the better of you, like it did with me at the end of last season's game when we scored in the last minute. It's an emotive game, we want to win.
"You have got to control your emotions because, at some point, there will be a flashpoint in the game. There will be a tackle that's mistimed and probably looks worse than it is, and it will be how you behave when that incident occurs.
"It's one of the great derbies of the world. I have been to many, many games, including the Glasgow derby, and this game is as venomous as that. It makes it electric.
"You don't want to lose that passion, but hopefully at the end of the game, everybody shakes hands, the better team has won and we all go home safely. That's important."
