For the 2015 FIFA Club World Cup final, Barcelona met with River Plate from the Argentine top flight and it was the Spanish team who emerged winners via a 3-0 win. Belgian national team defender Thomas Vermaelen was left on the bench at the start of the game and he would be introduced into it for the final ten minutes.

His presence was to keep things tight at the back and maintain the clean sheet until the end of the game.

Barcelona took the lead through star player Lionel Messi. His goal nine minutes from the interval gave the Catalan giants a slim advantage after 45 minutes. Luis Suarez added a second half brace to wrap up the 2015 FIFA Club World Cup title for Barcelona.
