Athletic Club face Real Madrid at San Mames this weekend and Aritz Aduriz has stated that his team need to play the perfect game in order to gain all three points.
The 36-year-old striker is aware of how strong Athletic are at home, having won 16 games from a possible 19 without losing, and a victory would allow the Basques to continue their quest for a European position.
"Real Madrid are one of the best teams out there," Aduriz claimed.
"They have some incredible players that can determine the game, and we know that in order to get a positive result, we need to play the perfect game.
"I think the team will be able to play a good game because we are a strong team at San Mames and, even though we have Madrid in our path, we have the ability to make things difficult."
Aduriz believes that a victory will be reliant on Athletic displaying more hunger and fight than Los Blancos.
"We must show maximum effort and concentration for the whole game," he continued.
"Madrid has the ability to make you think that you're dominating the game, and suddenly they score a goal or two or three, and that finishes the game.
"They have that capacity to appear like they're doing nothing and then appearing at any moment, so you have to be aware for the full 90 minutes and cannot neglect anything."
Real Madrid centre-back Sergio Ramos has scored some important goals this season, including one in a 2-1 victory against Real Betis last weekend.
"No, [his aerial ability] does not surprise me because I've been lucky enough to work with him for a month, to see him train, and he has an unbelievable ability to finish," said Aduriz.
"Whoever plays will try their best [to stop Ramos from set pieces], but not only him; Cristiano [Ronaldo], [Gareth] Bale and [Alvaro] Morata are all incredible and head the ball well."
While Aduriz was out, Inaki Williams deputised as striker and he is confident that he will be an important player for the Bilbao club in the years to come.
"Williams is a great player for Athletic," Aduriz stated.
"What happens is that, in football, everything goes so fast that we have absolutely no patience at all and we want things to happen instantly.
"Willy is a player with incredible ability, who is super young and can become very, very good."
When asked to give a result for Saturday's game, Aduriz was coy.
"I dare not to give a result, but an Athletic win would more than suffice," he finished.
