Barcelona forward Lionel Messi is looking to complete an "unforgettable" year with a fifth trophy when they play in the Fifa Club World Cup in Japan.

Barca, who face Guangzhou Evergrande in Thursday's semi-final, have won La Liga, the Copa del Rey, the Champions League and Uefa Super Cup in 2015.

In 2009 they won all six trophies, including the the Spanish Super Cup.

"That time we won, everything looked unrepeatable. We weren't sure if we'd get close to it again," Messi said.

"And here we are. Now what's left for us to do is end the year in the best possible way and make it unforgettable."

The final is on 20 December, also in Yokohama.

Neymar is an injury doubt for the semi-final with the Chinese Super League and Asian Champions League champions, having missed two games with a groin injury.

Barca are looking to win their third Club World Cup, which is for the champions of each continent and the national league champions of the host country.

Guangzhou, who are unbeaten in 28 games, are managed by ex-Chelsea boss Luiz Felipe Scolari and have former Premier League pair Robinho and Paulinho in their squad.

Japanese champions Sanfrecce Hiroshima face Argentina's Copa Libertadores holders River Plate in the other semi-final. The final is on Sunday.
