Tottenham head coach Ange Postecoglou has warned any proposal to introduce blue cards and sin bins will destroy football.
It was revealed on Thursday that a trial could commence soon where a blue card would be shown for dissent and professional fouls where the offenders would be sin binned for 10 minutes.
FIFA has since clarified the trial will not occur in elite football, while football's lawmakers, the International Football Association Board, will not publish plans for the sin bin trial until next month.
However, Postecoglou was unequivocal in his belief it would be a wrong move.
'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, mate,' Postecoglou insisted.
'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 talked at length about the laws of the game ahead of Saturday's visit of Brighton.
The Spurs boss defended goalkeeper Guglielmo Vicario, who conceded from another corner during last weekend's 2-2 draw at Everton.
Vicario failed to deal with Dwight McNeil's delivery into his six-yard area while under pressure from Jack Harrison, which was also the case in the 1-0 loss to Manchester City last month.
Ruben Dias crowded round Vicario on that occasion from a Kevin De Bruyne corner and the Tottenham goalkeeper's flap resulted in Nathan Ake scoring.
Spurs have written to Professional Game Match Officials Limited this week to get clarification over why both goals have not fallen under the bracket of encroachment.
'We have sent some stuff to get some clarification,' PostecoglouRead on m.allfootballapp.com
