Quique Setién has addressed the media at Camp Nou after the victory over FC Barcelona.

Match analysis: "Every time you come to this field you know you are going to suffer. However, if we have the personality, we are able to manage the pressure, and we use our mechanisms, we are able to play well and have the ball. Barcelona struggle without the ball and suffer to recover it. We were overwhelmed in the first minutes, they didn't allow us to get out our own area. We have two chances to score, though, but that phase was asphyxiating. Then we controlled the game well and had the accuracy on goal we lack some other days. I think we could have score some more. They also had good chances. I think we did a good game against a great team."

Mistakes: "Football is about mistakes and wise moves. There are always more mistakes than good moves in every game. Probably, fans of both Barcelona and Betis have suffered more than the rest, who probably enjoyed a great game. It was a game between two teams wanting to win, wanting the ball, brave sides. Barcelona has been creating a style for 25 years and we are trying to strengthen an idea that sometimes work and sometimes doesn't. We're solid about this. This is a huge backing to what we propose. We have to be proud of the players because they showed a lot of personality and read the game really well. We defended well and, even having chances to attack more, we showed composure and made Barcelona run after the ball. That allowed us to get to the end with easiness and have more chances."

Playing style: "There are a lot of people who are sceptic about this. Specially because winning is the only thing that matters. Sometimes you have to stop and think about how you do things. We are certain about this. The players have always been convinced about what we do. I'll always have this idea. I'm sure time will tell I'm right. We see how the team continues progressing, step by step, even if we you can through a negative streak like we did. Our conviction does not change. The strength of this team and this group is the most important thing. The dressing room is above everything else. We strongly believe in what we do and we accept it when it doesn't work. Now it's time to enjoy. The reality is that this is just three points and will soon be forgotten. We'll enjoy the moment and the satisfaction of thousand of fans who follow their team every day. The rest will be a memory for all of us. Winning here with four goals is something that will be there forever. A treasure."

Messi: "This victory has even more value because Messi was on the pitch. I didn't expect him to play. I spoke to him and told him that I wouldn't have taken the risk but he couldn't wait any longer. No matter if he loses an arm or a leg, he's good anyway. It's always better to see him playing."

Way of playing similar to Barcelona's style: "Barça fans have been watching this football for a long time. We are still learning, but we're on it. We manage many concepts that we are trying to apply. Even if sometimes it doesn't work, there are days, like today, when we feel proud of all the compliments we receive."

William Carvalho: "Today we saw his best. We knew he is extraordinary player. I think there's an issue with most of the players who played the World Cup. They are mentally tired. It also happened with Inui. I think we have to give them time. They are great players and we just have to wait. We have to give them the context in which they feel better. William is adapting to our way of playing, he's understanding it really well. It's a player who will give us a lot because he's really good."
