Athletic Bilbao coach Marcelo Bielsa has warned his men not to fall victim to referee decisions against Real Madrid on Saturday.
In recent visits to the Santiago Bernabeu, the Basque side have suffered from poor discipline, which caused them to travel home empty-handed.
“We must try not to avoid giving away refereeing decisions that can define the game, such as red cards, penalties or playing a game with many players booked,” the Argentine told reporters.
“Refereeing errors are not a determining factor overall. At the end of the year they usually balance out in terms of justice or, if not, bad luck.”
Bielsa went on to explain how Bilbao intend to match the reigning Liga champions on the tactical front.
“We respect them, but we want to make our presence felt,” the 57-year-old said.
“We always try to play (our own game). They negate counterattacking opportunities, but provide many balls to the attack. So that solves one problem and creates another.
“The solution is the hardest thing. We must try to play but not lose.”
