Tottenham manager Ange Postecoglou has warned any proposal to introduce blue cards and sin-bins could "destroy football".

It was said on Thursday a trial could soon commence where a blue card would be shown and offenders would be sin-binned for 10 minutes. 

And like fellow bosses Jurgen Klopp and Mauricio Pochettino, Postecoglou has slammed the idea.

He said: "One team being down to 10 men for 10 minutes, you know what it's going to do to our game? It's going to destroy it.

"You're going to have one team just sitting there trying to waste time for 10 minutes waiting for a guy to come on. 

"Every other sport is trying to declutter. All we're trying to do is go the other way for some bizarre reason."

Postecoglou also admitted that Spurs have contacted PGMOL about what constitutes a foul on a goalkeeper after recent controversy with Guglielmo Vicario. 

The Italian keeper conceded from another corner during last weekend’s 2-2 draw at Everton having also done so in the 1-0 loss to Manchester City last month. 

Ruben Dias crowded round Vicario on that occasion and the Tottenham goalkeeper’s flap resulted in Nathan Ake scoring.

Postecoglou added: "We have sent some stuff to get some clarification. 

"I'm going to get called out for this but there was a thing that was quite evident in the game that the goalkeeper was a protected species. 

"I don't think that's just me making that up. 

"The reason people used to say that was that if you impeded a goalkeeper in any way in the six-yard box, you are going to get a foul. 

"I knew that as a player, I knew that as a manager.

"I think there’s been a shift there. 

"It's pretty much opened it up that you can surround the goalkeeper and crowd him and put balls on top of him and just wait for the scramble to finish and see what happens."
