"It was an important goal but the most important thing was that we got the three points," the Brazilian told the club's official website.
"We played so well. We showed real concentration after we conceded the first goal and we were ready to score soon after.
"The Premier League is difficult and when you lose the first goal, you have to play well. We did that. We passed the ball well, kept possession and that was key. Then we scored the two goals. It was important to win this game."
Saturday's victory has seen Tottenham move up to sixth place in the Premier League table.
