Barcelona have clinched the Fifa Club World Cup for the third time with a comprehensive 3-0 victory over River Plate in Yokohama, Japan.
Messi fired home the opener just after the half-hour mark, and Suárez added a brace in the second half.
River Plate started brightly enough, but it was soon clear that the Argentinian side could not cope with Barca's front three once they were in full flow.
For their opener Neymar and Messi both had roles in the build-up before the Brazilian found his Argentine colleague to fire home the opener.
Suárez added a second from Busquets' excellent long ball and then headed home Neymar's excellent cross for his second.
It is Barça's fifth trophy of 2015 and, for the second time in his career, Lionel Messi has scored in all six club competitions in a year. Barça won the treble last season, and though Luis Enrique was rumoured to be on the verge of being sacked a this time last year, the club has since won five of the six trophies up for grabs in 2015. Only a Spanish Super Cup defeat by Athletic Bilbao denied them the chance to match the 2009 sextuple under Pep Guardiola.
They are currently sitting at the top of La Liga (on goal difference from Atlético Madrid, who play later on Sunday), and in the last 16 of the Copa del Rey and Champions League - as they bid to do it all again in 2016.
Barcelona have scored 176 goals this year - a new club record. They have one final game to add to it - at home to Real Betis in the league on 30 December.
