Arsenal boss Arsene Wenger won't underestimate Aston Villa ahead of the FA Cup final.

Arsenal may be favourites to retain the trophy, but Wenger knows that can count for nothing on match day, which for him makes the competition so appealing.

"If you are in the FA Cup everyone can dream of winning it at the start of the season, while the (Premier League) - only seven clubs can dream of winning it," said Wenger, whose last league crown came in the 'Invincibles' season of 2003-04.

"In the (Premier League) you can talk and talk, but we know the biggest budget will win it. That open dream is what makes (the FA Cup) special in football.

"In basketball if you play against a team from Division Two, there is absolutely no chance unless you give them 30 points (start), only our sport can create that excitement because it is uncertain."
