Barcelona coach Josep Guardiola believes his all conquering side will struggle to reach the levels they have during 2009 in the future.
The former Spain and Barca man was speaking at a press conference ahead of the weekend Club World Cup Final in Abu Dhabi, where his side face Argentine outfit Estudiantes.
He said: "The future is dark.
"Beating this is impossible. We would be wrong to compare other years with what we have done in this one. "
Influential midfielder Andres Iniesta will miss the clash with a leg muscle injury and Guardiola is disappointed for his talisman.
He added: "There is nothing worse that could have befallen him.
"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."
