Barcelona coach Pep Guardiola insists their glorious year will not be affected if they lose the Club World Cup final to Estudiantes.

Barca play their 64th and final competitive match of an historic 2009 against the Copa Libertadores champions in Abu Dhabi on Saturday, of which the Catalan giants have won 44 and lost just five.

However, even if Barca should come up short against Estudiantes, Guardiola believes their annus mirabilis will remain undiminished.

"This won't condition all that we've achieved," said Guardiola, who concedes life will probably never be as good as this again.

"The future is black, because it will be impossible to do better than we've done. Our obligation is to not stop working."
