Atletico Madrid goalkeeper Thibaut Courtois believes they can shock Real Madrid in the derby this weekend.
Atletico go into the game the form team.
Courtois, on loan to the club from Chelsea, told Marca: "We have a great team, we know how to beat them. (Playing for the) three points is (like) another final.
"As a player, you never play for a draw, you always play to win.
"There are players here who are in good form and others who are not, but I think the team as a whole can maintain the level and the spirit is good."
