By Carlo GarganeseWhether you like it or not, simulation is part of the FIFA 15. Driving it into extinction is completely unfeasible.To succeed, players must push the boundaries of fair play. Naivety doesn't win trophies. When defending a corner, for example, a little bit of pushing and pulling is absolutely essential for both physical and tactical reasons. When forming a wall at a free-kick, edging forward a yard can be the difference between avoiding and conceding a goal. Similarly, and no distinction should be made just because it is diving, there are scenarios where exaggerating or accentuating a fall is a necessary evil. "Play-acting?
