Players are unaware of the danger of being overly enthusiastic in their search for victory and attempting to draw the ball with clashes, some of which could lead to heavy "physical" losses that could outweigh technical motives, and turn stadiums from a source of joy to a gloom for the masses.

That's what happened during the Corinthians and San Carlos match in the Brazilian Futsal Championship, when Corinthians Daniel Batalia rushed and kicked the ball before his foot at the head of his opponent Fernandinho suddenly lost consciousness and fell to the ground.

The Spanish newspaper "Marca", which circulated the news on Thursday, accompanied by a video clip of the situation as "the worst offense in the world of football in the 21st century," said: "Fernandinho was taken to hospital immediately and the player regained consciousness and his condition is now stable."

Here is a video of the injury to the Brazilian player:
