Despite losing Cole Palmer in the warm-up to injury, Chelsea thrashed the hosts 5-1 on the night.
Cucurella said afterwards: "We are very happy. I think in the last game we missed something. I think we don't play our style but I think today, at the beginning, we started a little bit sloppy but the reaction from the team was very good. We showed a lot of energy. We want to play good football and we have a good result tonight."
On losing Palmer, the defender said: "It's difficult because we practice one thing, at the end we need to change very fast but I think Estevao, in this case, played an amazing game. I think it's very important because we have a good squad, all of us, we are ready at any time and we are very happy because we showed we have a good team."
On young teammate Estevao's performance, Cucurella added: "I think he's young but he showed that he's very mature. He made very good decisions and all the new players, all the new signings came here to help the team, to bring something good, good energy, good talent. I think we have an amazing squad, so I hope we can do good things this season."
