Mauricio Pochettino (talking to the BBC): "It was fantastic.
"It was a fantastic night, a very good performance from the team.
"I am very happy because I think tonight was the first time that there was the relation between the team and supporters.
"It was brilliant at White Hart Lane and I enjoyed it a lot tonight.
"I think some games we played very well but this result was important for us.
"It has home, it is in front of our supporters and we go to the semi-finals of the Capital One Cup.
"We know Tottenham have a lot of tradition in the cups and I think this victory is very important for us.
"I think that we need to have full respect for Sheffield United.
"It is a team from League One but they deserved to stay on to the semi-final.
"Yesterday we watched the game and they fully-deserved to stay in the semi-final.
"But we need now to stop and be focused on the Premier League. Saturday is a very important game for us and after, when we arrive in January, we will focus on this game.
"We fully respect them and in football you never know. We need to be careful, be ready and always alive in every game. It is not an easy game."
