While the 74-year-old manager did not go as far as to label the refereeing an outright error, he questioned the nature of the handball or foul that led to the equaliser.
“These situations sometimes turn out positively for you and sometimes negatively.
“We were unlucky today. It can be whistled, I accept it.
“But it was an unfortunate moment; the player cannot react at all.
“There is no intentional play there that he wants to prevent the ball from flying.
“I accept the whistle from the referee.
“I have a penalty in the box, severe, but whistleable,” Koubek admitted.
