Argentina’s River Plate completed the most remarkable transformation in the team’s history when they beat Mexican club Tigres 3-0 to guarantee their third Libertadores Cup triumph. The win came four years after the Buenos Aires club were relegated for the first time in over a century and means that, under the stewardship of Marcelo Gallardo, they now hold both of South America’s top club competitions, having won the Copa Sudamericana in December. “The history of this club is about fighting for these kind of competitions,” said midfielder Leonardo Ponzio. “Today is the greatest that you can achieve as a club and we did it.” Lucas Alario, the 22-year-old striker who only joined the club in July, got the opener on the stroke of half-time when he dived to glance home a curling cross from Leonel Vangioni. Carlos Sanchez was felled in the penalty box with 74 minutes gone and then hammered the spot kick past Nahuel Guzman before Ramiro Funes Mori sealed the victory when he rose to head home a corner four minutes later.The result gave River a 3-0 aggregate victory after the first leg in Monterrey ended scoreless.
