"They've played some hard games and they've had some indifferent results, but so have we. The thing we're looking for is a win,” he told Everton’s official website.
"I suppose the main thing we're looking at ahead of this game is mainly to concentrate on ourselves.
"We respect Newcastle, respect the players but we're going to make sure we give them a hard time."
And Cahill identified in-form striker Andy Carroll as the Magpies’ danger man.
"You know he's got a goal in him - he's a big boy who is very physical and he's got an eye for goal, not only with his head but also with his feet,” he added.
"He's going to be a danger and someone that we're going to have to look out for hopefully we can keep him under control."
