Torres missed a golden opportunity to open accounts earlier in the game when his attempt rattled the crossbar just before half-time.
He later redeemed himself with a last-gasp goal which he grabbed amidst confusion in Manuel Pellegrini’s defensive line.
"When it happens in a game like this against a great team like Manchester City, the last minutes of the game taste much better," the striker told reporters.
"I think 1-1 maybe was not the fair result of the game. I think we controlled the game most of the time. We created chances, especially in the first half,” he continued saying.
Sergio Aguero let loose an outstanding 49th minute strike past Chelsea’s defences, an emphatic answer to a goal by Andre Schurrle, putting the two teams level.
"But as you can see they have everything with players like Aguero. They can score a goal at any time.
"At the end, I think we won a game we deserved to win and we're happy because this is the first victory against one of the contenders for the Premier League.
"You never know which [moment] will become the most important of the game. It was a long ball, not the best understanding between the defender and the keeper and you win the game in that action.
"Every ball has to be the most important ball of the game because it can be the ball that gives you the lead."
Torres has been recently finding goal-scoring form, building up on his impressive Champions League double against Schalke earlier in the week.
Jose Mourinho was impressed by the strikers performance and his determination which led the 29-year old to nab his first Premier League goal since the start of the season.
"Everything happened for Torres after he missed an easy chance. After that, we saw the best Fernando," said Mourinho.
"He worked unbelievably for the team. The second goal was a 'believe goal.'"
