They'll play either Manchester City or United in the final.
Jose Mourinho is 90 minutes away from his first trophy as Tottenham Hotspur manager.
Goals in either half from Moussa Sissoko and Heung Min Son saw them beat Brentford by 2-goals to nil in last night's Carabao Cup semi-final at the new White Hart Lane.
Brentford's cause wasn't helped by the late sending off of Josh DaSilva.
Mourinho says attempting to win every game has given Spurs a chance of landing silverware for the first time in 13 years.
Spurs will play either Manchester United or Manchester City in April's final.
The neighbours meet at Old Trafford tonight from 7.45.
The game is likely to be preceded by more tributes to Colin Bell.
The City legend died yesterday following a short illness.
Bell made nearly 500 appearances for the blue side of Manchester, helping them to the title in 1968.
