The 33-year-old midfielder believes that dominating opponents is important and is excited by the prospect of potentially playing the Champions League final at Wembley again
The veteran midfielder has been as influential as ever this season, with the club on the brink of wrestling the Liga title from the grasp of Real Madrid.
The Blaugrana have also reached the last four of the Champions League, but despite the prospect of bolstering their reserves of silverware, Xavi believes that results are not always the ultimate barometer of quality.
"Other teams win and are happy, but it's not the same. The identity is lacking," the 33-year-old told Uefa's Champions magazine.
"In football the result is an impostor. You can do things really, really well but not win. There's something greater than the result, more lasting - a legacy."
"Barca always try to direct the game, they don't wait for the opposition but go out and attack, so people identify with the club. Barca fans would never understand if the team were not controlling or dominating a match. It's about doing something extra, not just winning. That's the way it has to be."
Tito Vilanova's side will face Bayern Munich in the semi-finals of the Champions League, and if they can overcome the Bavarians over two legs, the Camp Nou squad could be playing in the final at the stadium where they last lifted the European trophy two years ago.
"Wembley brings us a lot of joy," Xavi admitted. "We have been in two finals there and won both. Having the final at Wembley makes us dream of getting there again.
"It will be difficult but we want to be there with all the good feelings we've had in London and at Wembley in particular."
