YOKOHAMA (AFP) - Lionel Messi grabbed a brace as a rampant Barcelona out-classed the Brazilians Santos 4-0 to lift the Club World Cup on Sunday and confirm their status as the best team on the planet. The clash between the European and South American champions in Japan had been billed as a showdown between Messi, widely acknowledged as the best player in the world, and 19-year-old Brazilian sensation Neymar. In the event, it was no contest -- either between the two supreme talents or their teams -- as Barcelona picked up their second world crown after winning the competition in 2009. Messi, set up by Xavi, got the first after 17 minutes, before Xavi put Barcelona 2-0 up just seven minutes later to put them firmly in control, as prodigious forward Neymar struggled to get a sniff of the ball. Cesc Fabregas, who pulled the strings in midfield, got the third on the stroke of half-time as the Spanish champions, who were at full-strength, threatened to run riot for the full house of 68,166. Messi got his second eight minutes from time as he rounded the keeper to roll the ball in after the influential Dani Alves threaded the ball through to him. Barca, who lost striker David Villa to a fractured shin in Thursday's semi-final, had the better of an open first 15 minutes, Messi forcing a save out of Rafael Cabral after skipping a couple of half-hearted Santos challenges. Shortly after that the Argentine was at it again, taking a dinked pass from Xavi and lifting the ball delicately over Cabral from just a few yards out to put the Catalans into an early lead at the International Stadium in Yokohama. Meanwhile, Asian champions Al Sadd held their nerve to take third place at the Club World Cup on Sunday as they won their play-off against Japanese side Kashiwa Reysol 5-3 on penalties. Nadir Belhadj, who also scored the decisive penalty in a shoot-out in the AFC Champions League final last month, was again the hero for the side from Qatar as he scored their fifth. The clash went to spot kicks after a low-key game that ended 0-0 after 90 minutes -- there was no extra time -- and never really hit the heights. The first real chances of the match did not come until mid-way through the first half, when Kashiwa threatened three times in quick succession including a snap shot by midfielder Junya Tanaka that smacked an Al Sadd post. Moments later the Qatari side might have taken the lead on the break, but Mamadou Niang saw his powerful shot parried by Takanori Sugeno, who 10 minutes before half-time also denied Abdul Kader Keita. The second half took on a similar theme, the Japanese side having most of the ball without really creating any concrete openings and Al Sadd defending in numbers while looking to counter-attack at International Stadium Yokohama. Niang might have grabbed a winner in the dying minutes, but his shot was deflected and the ball looped over the bar, sending the contest to penalties.
