Tottenham's penalty shootout win over Hull in the League Cup was not down to practice, Andre Villas-Boas said.
Spurs won a marathon shoot-out 8-7 when Brad Friedel saved Ahmed Elmohamady's effort to advance to the quarter-finals after extra-time finished 2-2 at White Hart Lane.
It was Tottenham's first shoot-out win since 1994, setting up a showdown with London rivals West Ham in the last eight.
"We practiced and practiced penalties for the Basel game last year, but we didn't this time," Villas-Boas said.
"We haven't practiced them for three or four months.
"We've seen some brilliant, brilliant football tonight. If you want to see predictable endings or happy endings you go to the opera or the theatre.
"In football you don't know what is going to happen. I couldn't be happier."
Gylfi Sigurdsson put Spurs ahead with a brilliant goal in the 16th minute before Friedel's own goal sent the tie to extra-time.
Paul McShane scored first for the visitors in the additional half hour but Harry Kane levelled the scores to set up a thrilling shootout.
