Barcelona midfielder Andres Iniesta says they must not dwell on their Super Cup defeat.
Barca surrendered the title to Athletic Bilbao 5-1 on aggregate.
"Now we have to focus on the start of La Liga," said Iniesta.
The captain is adamant that the 'Azulgranas' must now look forward with optimism and turn their attention to "all the exciting challenges that lie ahead of us".
