Basically the whole idea of this blue card sin-bins is to punish players that have committed foul against another player, so when the referee shows you blue card, you are to go outside and stay for 10 minutes while the game will still be going on, you will remain there for 10 minutes then you come back afterwards and continue with the game, however this does not take the place of yellow card and the red card.
So guys how do you see this new intended innovation, is it going to change the face of football across the world, let's have your opinion.

This doesn't sound like it makes any sense to me because how can you take out a player from a team of 11 players and keep the player off the game for 10 minutes while the game is still on? Who does that?
Since a team usually have 10 players and a goalkeepers to make it 11, if you take out one player, it means you will only have 10 players on the field for that team. If you keep the player out for 10 minutes, that means only 10 players will be active for the 50 minutes that the match will go on.
Again, what if it was three players who were the victims of a blue card? Does it mean that three players will be taken out while only seven players continue the game?
This is not going to be a fair thing to be introduced to football because it can cause a team to lose even if they were supposed to win. I am not in support of such a thing.
