"It was an important win, especially after the defeat against Spurs," said the Brazil international.
"It was a heavy defeat at Spurs (4-0 - in which they had two men sent off) and it was important to win in the Carling Cup and get three points in the Premier League which gives us chance to be close to the top four.
"Of course against Spurs everyone could see the situation of the game when we lost two men and it is always difficult to come back.
"Against Stoke we didn't deserve to lose because we played very good football but when you have two defeats in a row the confidence gets low.
"We spoke before the game against Brighton that we needed to win, get back on track and go into the next round and come into this game with confidence and win and that is what happened."
