Curiously, Xavi is one of those who advocates increasing the effective playing time, stopping it or increasing the extra time, I don't remember exactly, but he once said so.
In any case, in Spain the slightest contact is a foul and rough games usually end up with many cards, especially if there are guys like Mateu Lahoz. That's why if the referee allows a lot, it's called European refereeing.
Then there are masters in stopping the game with constant tactical fouls (I believe that in general, not only in Spain, this type of fouls should be punished much more, as well as the repetition) and getting rid of the yellow card, Gavi is one (and Casemiro was another).
