David James has admitted he is desperate to finish on the winning side at the third time of asking in an FA Cup final.
James was a member of the Liverpool team that lost to Manchester United in the 1996 final and was then at Aston Villa when they were beaten by Chelsea in 2000.
The 37-year-old goalkeeper will line up for Portsmouth against Cardiff on Saturday and he has called on his team-mates to deliver a good performance.
"I've been here twice before, with Liverpool in 1996 and with Aston Villa in 2000," James recalled in The Sun.
"On both occasions the build-up was great but the performance was sub-standard. People tell me it's third time lucky but I don't believe in luck.
"In my two previous cup finals we didn't play well enough and deserved to lose. It was so frustrating.
"All I can hope for this time is that we go out there and give a good account of ourselves."
Pompey have had to battle through each round to reach the Wembley showpiece and James is anticipating another tough encounter.
He said: "We've won four ties 1-0 and the other 2-1. it hasn't been pretty but we've done enough to go through.
"I'd like to think the final will be a fantastic spectacle but I'll settle for another one-goal win.
"If we do, then a very good season ends up being a tremendous one."
