The News Agency of Nigeria (NAN) reports that Liverpool, with this win, remain third in the English Premier League table.
Quizzed as to whether super-subs Coutinho and Firmino could have started the game, such was their impact from the bench, Klopp added: "It was like, as we understood it, the possibility was pretty high that we would have to change one of them after 30 minutes".
Jurgen Klopp defends his decision to rest Brazilian duo Philippe Coutinho and Roberto Firmino. However Klopp's risk didn't pay off as the visitors produced a tepid first-half performance and deservedly fell behind just before the interval, albeit in controversial circumstances.
"He came to me this morning at the hotel and said "I'm fine" but we knew he would have low energy levels".
Manchester City, who are fourth, are two points worse off with a game in hand.
"Firmino after the last game had a bit of a groin problem and was a bit exhausted, maybe he could have started but we had to leave him out of training for three days, so it was his first session today!"
But the Reds would still have suffered defeat were it not for their man between the sticks, with Mignolet producing a pair of incredible saves to deny Charlie Adam and Saido Berahino.
"When a goalkeeper makes saves like that, it's like scoring a goal".
But both Brazilians came on at half-time to score both goals and save Klopp's bacon - Coutinho finally equalising by smashing home inside the box and has now scored more Premier League goals than any other Brazilian in the competition's history.
"Those players didn't celebrate immediately with the boys", he said.
We could not see that ball behind the goal, that affected the players, when Firmino hit that bullet of a shot, mate, the red mist was still there, and the red mist is up here with me at the moment.
"It's not about them".
But, if Coutinho seemed as though he was off his game, perhaps it was due to the significant toll his sickness had taken on him.
As for Mark Hughes and Stoke, they go 13th, eight points clear of the relegation zone.
"It's a hard result to take".
"They created three clear-cut chances and scored two of them and we created more than that and only scored one - it's just the way things are going for us at the moment".
