Sheffield - Mauricio Pochettino said he was proud of his Tottenham Hotspur players after they reached the League Cup final but challenged his players to learn to "kill games".
Tottenham will face London rivals Chelsea at Wembley on March 1 after prevailing 3-2 against Sheffield United over two legs in the semi-final.
"We know that in England the special thing is to get to Wembley and play in the final. I'm proud of my players," Pochettino said.
"The lesson for us is you need to kill the game.
"You play with emotion and sometimes we see what happened at Sheffield United.
"We have a young team and they will learn from that experience.
"In football, you need to kill and to score when you have the possibility because we created the chances."
Tottenham's trip to Wembley is their first in a final since 2009. They can take confidence from the fact that they beat them 5-3 on January 1.
