Liverpool manager Jurgen Klopp has panned the concept of a new blue card in football and claimed law-makers IFAB have never come up with any good ideas.
Klopp joined fans and pundits in the backlash against the blue card and 10-minute sin-bin idea put forward by the International Football Association Board this week.
A broader trial had been planned - potentially in FA Cup games - next season after sin-bins had been introduced in some youth and amateur matches.
The idea was unlikely to be introduced into professional football for some time but Klopp made clear his belief a third card would complicate things.
