The goalkeeper called the Black Cats achievement in staying up "incredible" but insisted they should not have been in trouble in the first place.
Sunderland goalkeeper Vito Mannone has told BBC Newcastle that although the club's late surge to safety has been "incredible", he is annoyed that they were drawn into yet another relegation battle this season.
The Black Cats secured their survival with a 3-0 victory over a lifeless Everton on Wednesday night, having spent more time in the relegation zone this season than any other club including hopeless bottom side Aston Villa.
Sam Allardyce's side won three of their final five and lost just one of their final 10 matches to surge from second-bottom of the league to safety with one fixture to spare.
Though the victory over the Toffes, like the euphoric comeback win over Chelsea on Saturday, sparked wild celebrations at the Stadium of Light, Mannone admitted that he could not help but be left feeling frustrated with how the club's season has panned out.
The Italian, who established himself as Allardyce's number one after Costel Pantilimon's January departure, told BBC Newcastle: "We've done something incredible, but we've got to learn now not to put ourselves in the same situation.
"I'm annoyed that we have not avoided it. We've got a good squad, a good coaching staff and a good manager - and it needs to be a base for us to push on now."
After enduring another tense, bitter relegation battle this season Sunderland will de desperate to avoid the same struggles next campaign, and will surely look to reward Allardyce with an extended stay at the club after he resurrected their top-flight status.
