Another Man of the Match performance from City's Swiss defender
Klose, named Anglian Home Improvements Player of the Month ahead of kick-off, rose highest on the verge of half-time to meet Robbie Brady's free-kick and score his first for the Club to put City in front.
Alexsandar Mitrovic levelled in the second period, then struck again to cancel out a fine effort from the outstanding Dieumerci Mbokani to seemingly leave the game certain for a stalemate heading into injury-time.
That wasn't to be the case however, with Martin Olsson striking in dramatic circumstances to seal an invaluable three points for Alex Neil's men in their battle for survival.
"It feels fantastic to come back," the Switzerland international told Norwich City TV when reflecting on a pulsating climax to the game.
"At 2-2 everything was against us, and [John] Ruddy has made a good save. We managed to score in the final minute, and the important thing is we're alive.
"As a team we are working to stay up. We're doing everything we can do during the week to be as good as possible.
"That's showing every week now. It was fantastic to score, but the biggest thing was winning the game."
The 27-year-old believes recent performances are now being duly rewarded, with the Canaries having amassed seven points from their last three outings.
"Some games before we've not had luck on our side," he explained, while remaining keen to look forward to upcoming fixtures.
"This time we did, and it felt fantastic to win the game. I'm very happy at the moment because we've got two big wins in our last two games.
"We've got more big games coming up. We want to take points from those as well."
