The 33-year-old former Austrian international won his domestic cup, and completed a league double, with Austria Vienna in 2003 and won the Norwegian Cup with Brann Bergen in 2004.
He would like nothing more than a third winner's medal on Saturday - especially as he threw the runners-up medal he got after Wigan lost 4-0 to Manchester United in the 2006 League Cup final into the crowd after the game.
"I won the cup in Austria and in Norway and England is my third country so it would be the perfect thing to win it in England as well," Scharner, who is on loan from SV Hamburg, told BBC Radio Manchester as Wigan prepared for their first FA Cup final.
After confirming that he expects to return to the Bundesliga at the end of the season, Scharner recalled how he felt at the end of Wigan's only other major final when they were well beaten by United.
"I was so angry that we lost, but to be honest, Manchester United were on a high.
"Cristiano Ronaldo was on a very good spell and it would have been very difficult to get something from that game.
"I got a response from the fan who caught the medal a couple of months later and it was really nice to read the card. I think he's happier with the medal than me," he said.
"I don't have scandals and I don't fight in bars, so I decided the simplest way to get some attention was coloured hair. The first time I did it was when I was 22 and since then I've had about 12 different haircuts and colours," he said.
"It's something people can talk about and smile about. Football is entertaining and people pay a lot of money to see us playing on the pitch, so you have to give something back."
