River Plate kept alive their Copa Libertadores title defence by once again getting the better of their fierce rivals Boca Juniors on Tuesday to reach the final. Despite losing the second leg of the semi-final 1-0 at Boca's Bombonera stadium - courtesy of Jan Hurtado's 80th minute goal - River progressed 2-1 on aggregate. The match, which came less than a year after <a href="https://www.thenational.ae/sport/football/copa-libertadores-final-postponed-after-shameful-attack-on-boca-juniors-bus-in-pictures-1.795534">violence interrupted the competition final</a> between the same two clubs, was delayed for 15 minutes due to the amount of ticker tape on the pitch but passed without any major security incidents. Last year the second leg of the final was <a href="https://www.thenational.ae/sport/football/real-madrid-s-bernabeu-to-host-all-argentine-copa-libertadores-final-1.797548">moved to Spain</a> after River fans attacked the Boca coach as it neared River Plate's Monumental stadium. And in 2015 Boca were kicked out of the competition after their fans attacked the River players with pepper spray in the tunnel at half time of their last 16 tie. Tuesday's result means that River meet either Flamengo or Gremio in the final planned for Santiago, Chile on November 23. The two Brazilian sides meet on Wednesday's second leg in Rio, with the tie balanced at 1-1 after the first leg in Porto Alegre.
