The Londoner insists his 'sudden' emergence due to an injury to Holland international Tim Krul has taken him eight years and included spells at Erith, Bishop's Stortford and Accrington Stanley.
He told the Sunday Mirror: "I have to pinch myself to believe.
"I'm now playing in the Premier League and Europa League. I've played in the lowest league in the non-league pyramid with Erith Town, when I was 17, and just worked my way up in stages.
"The ambition to play in the Premier League has always been there. But having been where I have, I probably relish it more.
"Some times you look around and appreciate the things you get, like travelling on a plane to Russia and playing against Samuel Eto'o, who has probably won everything there is to win apart from the World Cup.
"Now I just want to enjoy it. I don't want any regrets. I want to come away and say I did everything I could."
