Raymond van Barneveld believes he was a worthy winner of the Premier League title but admits Phil Taylor's semi-final mistake was a turning point.
Van Barneveld beat Taylor - for the first time in the Premier League - to set up the final showdown with world number one Michael van Gerwen, a match he won 10-6 to win the championship.
Van Barneveld felt he was good value for the title but acknowledged the importance of a key moment in his win over Taylor, a victory secured at the 21st time of asking.
"I played a very good Premier League, I only lost three matches in 16 weeks so I had 12 weeks undefeated," he said.
"I knew I could do it. The feeling was good. I must say that Phil let me back in the match. He missed six darts at a crucial time of the match.
"He let me in and I took over to win the five straight legs, the whole game and the whole tournament. It's all about belief. If you don't feel you can do it then you won't."
Van Barneveld's win was against the odds, with fellow Dutchman van Gerwen the clear favourite to win the final as the top-ranked player in the world and reigning champion.
By contrast, van Barneveld was included after being given a tournament wild card but was delighted to repay the faith of the Professional Darts Corporation (PDC) and the support of tournament broadcasters Sky Sports and the fans in attendance.
"I was very happy when I got the wild card," he said. "I've had that for the past three years and it means a lot. It means I'm still popular wherever I play and the crowd are still singing my name.
"The PDC and Sky still know that people buy tickets to see Barney and for me it's a way of saying thank-you to those fans and to Sky and the PDC by winning the Premier League."
