"There's no way I'm going to pack up. It's never entered my mind," said Redknapp, who this season has had his house raided by anti-corruption police and is still mourning the death of sister-in-law Pat Lampard, mother of Chelsea midfielder Frank, last month.
"I don't know what I would do without football and there's no way I am going to walk away from Portsmouth again. I've done that once and we all know what happened."
The 61-year-old was referring to his brief flirtation with south-coast rivals Southampton after leaving Fratton Park in November 2004 because of differences with then owner Milan Mandaric before returning a year later.
Some pundits took his low-key reaction to the Wembley victory as a sign Redknapp had finally had enough of management.
But, especially in light of recent events, he said it was just not his style to jump around on the touchline.
"I don't go mad at anything anymore. It takes a lot to get me excited," he said. "It's been difficult. My wife has been so low and I suppose it's not been easy the last few weeks but it can happen to every family at any time.
"It's hard for me when she's like that but I wanted to win so badly to get a smile back on her face and she knew how much it meant and was so happy about how the day went."
