And the Bluebirds boss says he even told his players ‘not to breathe’ on Manchester United’s stars in their recent 5-1 defeat at Old Trafford.
The Spurs clash will see Warnock’s defence pitted against the Premier League’s joint-top scorer Harry Kane.
Kane was cautioned for simulation against Wolves in Spurs’ recent 3-1 loss at Wembley.
And Warnock has warned his side to expect the same when they host Kane and Co. at the Cardiff City Stadium.

“It’s so difficult to see diving, you can’t blame referees,” he said.
“I say to my players about the top players ‘try not to breathe on them’.
“I said that before the Manchester United game, if they get in the box ‘Don’t breathe on them at all’ because they’ll be down. That’s how it is nowadays.”
Diving has come under the microscope once again after three high-profile incidents over the festive period.
As well as Kane seeing yellow for his antics, Liverpool’s Mohamed Salah won soft penalties against Newcastle and Arsenal.
Former Premier League referee Mark Clattenburg has urged officials to clamp down by dishing out more severe punishments and says the current rules are doing nothing to stamp it out.
“If referee Michael Oliver had decided Salah dived against Arsenal, Salah would have received no punishment other than a caution,” he said.
“But if the panel decided retrospectively that he dived, he would receive a ban. It’s flawed. The only way to kill diving is if the FA are strong.
“People have said Salah did not dive against Newcastle on Boxing Day, so are we saying that contact was enough to knock him down?
“What will happen when video technology comes in? Will they see that hand on his left arm and decide it is a spot-kick?
“If a player has a chance of scoring, hitting the deck is not in his head. Look back at Sergio Aguero’s goal against QPR to win the title for Manchester City in 2012.
“How many chances did he have to go down? He didn’t because all he wanted to do was score.
“Salah was not likely to score from either of the positions he was in against Newcastle or Arsenal, and neither was Kane.
“These are the incidents the FA should be trying to stamp out.”
