Atletico Madrid midfielder Koke insists they're capable of beating Real Madrid today.
Diego Simeone's men were unexpectedly beaten 3-0 at Osasuna last weekend and have slipped three points behind leaders Real, with just goal difference separating them from second-placed Barcelona.
"The truth is that we believe in ourselves," Koke said.
"We have had a long week although sometimes we prefer to play. We had a week to work on individual aspects of each player and it has been good for us to be able to improve in order to play a good match on Sunday.
"Our fans always want to win a title. For the club it is important to be in the Champions League and create a great long-term project. I think the goals are being met.
"We are aware that we come from a major defeat because of the importance of the result. We are behind them but we have worked hard during the week to improve on the mistakes we made in the previous match."
