Uwe Rosler is cannily playing the underdog, saying his Wigan Athletic side have nothing to lose against the mighty Arsenal.
The Latics may be in the mix for the Championship play-offs and a swift return to the Premier League, but Rosler has done his best to increase the pressure on an Arsenal side desperate to end their nine-year trophy drought.
And despite being FA Cup holders, with a perfect record at Wembley of two games played, two won without conceding a goal, Wigan are clearly second-favourites to make The Final.

Arsenal, by contrast, have lost both of their previous games at Wembley but Rosler says: "We are going to Wembley where we meet a top Premier League team, as the massive underdog.
"We'll face an opposition who will be on top for the majority of the game so I'm sure the players will appreciate the supporters throughout.
"We will need strong support to carry us through difficult periods in the game."
That was how Wigan managed to beat Manchester City in last season's memorable Final victory, masterminded by Roberto Martinez.
And the Spaniard showed Rosler the way to beat Arsenal, when his Everton side won 3-0 at Goodison Park last week.

But the German manager is taking little notice of that result and claimed: "In many ways, Arsenal's defeat at Everton last Sunday didn't help us because it puts even more pressure on Arsenal to absolutely go for it and to win a trophy this year with their Champions League place under threat.
"We have to make sure we stay in the game as long as possible and give ourselves a chance the longer the game goes on to get through to The Final - we have to make ourselves strong opposition for the Arsenal team."
Ben Watson, scorer of the goal that won The Cup last season, is still absent with a broken leg, but man-of-the-match Callum McManaman and Jordi Gomez are likely to return to the side.
