The bottom-of-the-table Reds travel to New York on Saturday night to meet the Red Bulls, sitting fourth in the East, and the Australian is of the belief that the Canadian club will come with a winning mentality in a bid to get something from their disappointing season.
"Toronto have got nothing to lose," Cahill said. "They're coming and they're going to throw the kitchen sink at us.
"They're going to want to beat New York at home and that's an even bigger incentive."
And Cahill's teammate, Thierry Henry, feels it will be a much tougher match between the two sides that what it shows on paper.
"They're going to make it difficult," Henry said. "They're very direct, although I saw them playing in the CONCACAF game and they were not playing that long. They were playing the ball on the ground and passing the ball around.
"Everything is down to us, no disrespect to Toronto. But if we give them the space and the time to play well at the beginning, they are going to punish us like all the teams that punished us when we give them space. Simple as that."
