Roberto spoke about the importance of having earned a point against Villarreal in the 4-4 thriller on Tuesday.
"(It was a) crazy game. It seemed like it would be comfortable for us but they are fighting against relegation. At 4-2 down we went for it and we got a point."
On the Atletico Madrid clash on Saturday: "We knew Atletico had won and we looked to get a point until the end, the point is good and we will play for it all on Saturday.
"We want La Liga, then the Champions League and the Copa del Rey. Now it's league and against Atletico it will be a vital game, a final. If we get the win it will be very important for us."
