Paolo Di Canio has declared he ready to return to the game as a better manager.
Di Canio was sacked by Sunderland after just five games of the 2013/14 Premier League season with the Black Cats bottom of the table.
But his successor Gus Poyet was able to lift the Wearsiders to the Capital One Cup final and eventual top-flight safety.
The Italian insisted he had performed a miracle to keep Sunderland in the Premier League the previous season when he took over from Martin O'Neill on March 31, after a successful spell at the helm of Swindon.
He told Sky Sports News: "I'm pleased for the fans. They're very passionate, so I'm very happy they stayed up.
"We made a miracle (in 2013) because the team came from a very bad run.
"We changed things in a short period which is very, very difficult. It's like a miracle because if you've got seven or eight months you can change things, you can deliver your philosophy.
"I didn't have a long time to deliver or fix things. There was a project and after five games they changed their minds. It's not a problem now, I have to look forward.
"In two years of my career I only had a successful period so that proved my philosophy, in general, is the right one. "
Though Di Canio is eager for a quick return to management, he would like to come back on his own terms, and refused to comment on returning to West Ham.
Di Canio insisted Sam Allardyce was doing a good job with the Hammers and added: "It's not the time, I will answer when it will be the time.
"It's not fair to talk about it now, he's a manager who's got great experience, and had a long time in Premier League.
"The (West Ham fans) sometimes like (his style), sometimes don't. I don't know why they're so frustrated. You should ask them to be honest. I can only tell you that Sam Allardyce is a good, experienced manager."
He reiterated his desire to return as a manager, saying: "I'm available, I'm ready. I've had time to think (about) what's happened in the past. I have a more positive opinion about my philosophy."
