Barcelona coach Josep Guardiola predicts darker times ahead for the Blaugrana simply because things cannot get any better relative to the club's current run of form."The future is dark", began the Barca coach in his pre-match press conference before tomorrow's Club World Cup final against Argentina's Estudiantes. "Beating this is impossible. We would be wrong to compare other years with what we have done in this one. What we need to keep doing is keep working. The fans will continue to be proud of us if we work."Guardiola also expelled the notion that Barcelona were in Abu Dhabi to compensate for having been unable to secure the trophy in seasons past. Finally, the coach lamented the absence of midfielder Andres Iniesta as the Spanish international will miss the final with a torn leg muscle."There is nothing worse that could have befallen him [Iniesta]. If anyone merits playing in the final, for his generosity, for the effort he put in in the Champions League final, for the goal he scored against Chelsea [in the semi-final], it is him. That Andres will miss this match is very poor".
