The 32-year-old is one of only two survivors from Wigan's last appearance in a major cup final, the 2006 Carling Cup defeat to Manchester United.
Goalkeeper Mike Pollitt, who has been ruled out for the rest of the season with a thigh injury, is the only other Latics player who featured in that game, which Wigan lost 4-0.
That match was played at Cardiff's Millennium Stadium, however, and with Wigan now just 90 minutes away from an FA Cup semi-final appearance at Wembley thanks to Sunday's win over Huddersfield, Scharner has revealed it has always been his ambition to play there.
"I remember very well getting to the final of the Carling Cup back in 2006 in my first year with Wigan," Scharner told wigantoday.net
"The game was played at the Millennium Stadium down in Cardiff, which was okay I suppose but it wasn't Wembley Stadium.
"Everyone wants to play at Wembley whether you are from England or overseas, and it is a big target for me this year.
"Wherever you go in the world, everyone knows about Wembley Stadium - and it would be a dream for me to play there for Wigan Athletic."
To make his dream a reality, Wigan will need to beat either Oldham or Everton in the last eight, with the two sides still to battle it out for a place in the quarter-finals in a fifth round replay at the end of the month.
Scharner added: "At this stage of the cup, everybody should just enjoy the moment because we are only one game away from a Wembley semi-final now, and obviously then it's only 90 minutes to the final."
