Was there anything David Nalbandian couldn't have achieved had he simply a penchant for consistency?
At his best, it was an accepted truth that he could compete with and outplay the very best in the world. Although he never reached the No. 1 ranking, there were certain times during his career where he was for sure the unofficial best player in the world.
His slew of achievements was impressive. Ultimately, though, they lack that all-important Grand Slam title. Like Safin, he is one of a few players to have reached the semifinal in all the Grand Slam events. He even reached the Wimbledon final in 2002, albeit losing weakly in straight sets to Lleyton Hewitt.
Such, though, was the man's talent that despite injury layoffs and bad form, he defeated Federer in his prime to win the World Tour Finals in 2005—his biggest title to date.
In 2007, he defeated Rafael Nadal in two consecutive tournaments in straight sets. At the Madrid Masters event that year, at the age of 25, he made history by defeating Nadal, Novak Djokovic and Federer to become one of only three players to have ever beaten the top three players in the world in a single tournament.
Nalbandian was (and still is) very talented, but injuries and poor performances at crucial stages have hampered him. He began 2011 ranked outside the top 20 and said he hoped to reach the top 10 at some stage. As of today, he is ranked No. 25.
