It was certainly a surprise to see the Premier League rivalry get to the final considering most would have thought no one outside of London would really care about it.
But the London sides could only finish fourth in the final, with the Old Firm finishing in third just behind Istanbul's fiery rivalry and Boca and River topped it all.
LAST FOUR: Vote on the biggest rivalry in world football :point_down:- SPORTbible (@sportbible) September 21, 2019
Last year the two Buenos Aires sides faced each other over two legs in the final of South America's Copa Libertadores.
The first leg finished 2-2 at Boca's La Bombonera stadium but the second leg had to be abandoned ahead of kick off because of crowd trouble outside of River's stadium.
The second game had to be moved to a neutral venue, with Real Madrid's Bernabeu hosting the first Copa Libertadores final outside of South America.
River won 3-1 in the Spanish capital to take the title.
