Gerard Houllier refused to take credit for the double substitution which spared Aston Villa's blushes and booked them a Carling Cup quarter-final spot.
Manager Houllier brought on Emile Heskey and Stewart Downing and both responded with a goal to earn his side a 2-1 success over Burnley at Villa Park after extra-time.
Heskey looked to have won the tie in normal time before Clark Carlisle's last gasp equaliser but then Downing's stunning strike sealed a last eight place.
Houllier said: "I don't take credit for the subs. The manager makes the decision to bring them on - but it's down to them.
"They scored the goals, I didn't. I wanted to rest some players but I knew at some stage, with other players tiring, they would make a difference.
"Emile made a difference and Stewart made a difference.
"The problem with the subs is they have got to be in the right frame of mind. If they have the right attitude, if the hunger is there, then they bring something.
"Their freshness can bring initiative which was the case. Emile came on and changed the game because he held the ball up."
Houllier, who lost John Carew through illness before the game, was full of praise for Burnley. He said: "Credit to them, they played well. We made it difficult. We should have scored at least one in the first half.
"That affected our confidence. We didn't play as well as we should have done in the second half. They really wanted it, credit to them. We really wanted it too, which is good."
Villa ended the game with 10 men after winger Marc Albrighton was red carded for a professional foul on Burnley sub Wade Elliott and he will be suspended for Sunday's derby with Birmingham City.
Houllier said: "To me, Albrighton's sending off was a fair decision.
"He didn't touch him (Elliott) a lot but he touched him and the player used it as if he had been shot dead - but he touched him.
"From Marc's point of view, he should have reacted quicker. This is one of the main progresses we have to do.
"You need sometimes to have game awareness and next time he will understand that."
