We wouldn't know if they are already acting it or not.We do see underdogs beat up top tier teams which most question and controversies pop out.
On some night an under dog can show more character and defeat a top team I don't see not controversy in this. The time FC Porto won the UEFA Champions league it's was unbelievable. Football is a game of 11 team members on the pitch like I said its a matter of character on the night not pen on paper
