More than ever, I am convinced that 'futbol' is a religion and the pitches are holy ground.
I was watching the Costa Rica/Italy game and saw two players crash into each other and lie on the ground clutching their legs, it looked bad. Someone will have to be taken off the field on a stretcher?
The collision was replayed on the tele and by the time they went back to the live shot of the field, Both players were up and back in the game.
I think that as soon as a player gets hurt and falls to the ground, the grass heals them?
That is the only reason I can think that their miraculous recovery comes to pass.
