Jose Mourinho is reluctant to tear up his attacking blueprint despite seeing Chelsea allow a Capital One Cup semi-final place to slip from their grasp.
Sunderland midfielder Lee Cattermole's 46th-minute own goal gave the visitors a lead they held until two minutes from the final whistle at the Stadium of Light, but their failure to build upon it proved fatal as the Black Cats staged a stunning fightback.
Mourinho later admitted he was considering adopting a more conservative approach after a series of matches in which his players have not made their periods of pressure count, but he is loathe to send them out with the intention of winning 1-0.
He said: "If I want to win 1-0, I think I can. One of the easiest things in football is to win 1-0.
"It's not so difficult. You structure your team from the back, you organise your team from the defensive idea, you don't give freedom to your players.
"The dynamic of the team is defensive and what you do is you recover the ball and try to punish the opponent. To win 1-0 is not the most difficult thing in football."
Chelsea had one foot in the last four when former Blues trainee Fabio Borini levelled.
Fellow substitute Ki Sung-yueng wrote himself into the headlines as extra time drew to a close, cutting inside to smash a low shot past keeper Mark Schwarzer to leave Mourinho contemplating a less offensive method.
He said: "I don't want to because we are going in a direction which is the right direction in terms of the quality of football we want to play, and it's quite frustrating that you have to change that and go one step back and go in another direction just because you want better results.
"It's something that I don't want to do."
