Tottenham boss, Mauricio Pochettino has said that 'you need to kill' in football when you create a lot of chances.
Tottenham boss Mauricio Pochettino accepted his side almost paid the price for failing to kill off Sheffield United early in their Capital One Cup semi-final.
Christian Eriksen struck just two minutes from the end of a pulsating second leg at Bramall Lane as Spurs snuffed out a dramatic late Blades comeback to secure a 3-2 aggregate win.
Pochettino said: "I am very happy - happy for our players because they deserved it. It has been a big effort in all competitions, in all games, since the beginning of the season.
"I think that if we analyse the two games, the first and the second leg, I think we deserve to be in the final. But in football you need to kill - this is a lesson for us. When you create a lot of chances you need to kill.
"Afterwards the game changed and sometimes it happens, what we saw today."
