Real Madrid boss Zinedine Zidane has claimed that Athletic Bilbao will provide him with his toughest test since being appointed head coach of Los Blancos.
The Frenchman has won four and drawn one of his five games in the hotseat, including all three home matches - scoring 16 times and conceding just once in the process.
Zidane has admitted that his side will not be able to keep up their flow of goals and would be prepared to accept a 1-0 victory against Bilbao on Saturday.
"Athletic are very strong, they're a very good team. We know which type of team we'll be playing. They will be our most difficult opponents at home since my arrival," Zidane told reporters.
"I'll be happy if we win 1-0. We can't always score five or six goals. We must give our best and prepare for what lies ahead."
Real Madrid will enter the match in third position in the La Liga table - four points off the leaders Barcelona and one shy of second-placed Atletico Madrid.
