Paris: Argentina's Juan Ignacio Chela shattered Alejandro Falla's dreams of becoming the first Colombian man to reach a Grand Slam quarter-final with a five-set, last-16 French Open triumph on Monday.
Chela won their four-hour clash 4-6, 6-2, 1-6, 7-6 (7/5), 6-2 and will face either British fourth seed Andy Murray or Serbia's Victor Troicki for a place in the semi-finals.
The 31-year-old Argentine matched his best Grand Slam performance with his win on Monday, having also reached the last eight in 2004, where he was defeated by Britain's Tim Henman.
Falla, the world number 120, had come through qualifying and by reaching the fourth round he had achieved his best result at a major.
The Colombian left-hander gave Roger Federer a huge fright in the Wimbledon first round last year when he took a two sets to love lead and served for the match at 5-4 in the fourth before his nerve failed him.
