Roger Federer is the active player with the most ATP Tour titles to his name, having won 103 tournaments over an illustrious career spanning more than two decades. The Swiss has also completed the Career Grand Slam, winning all four Majors at least once.
But he isn't without his failings. Despite his unprecedented success over the years, there have been a few events that have never been conquered by the 20-time Grand Slam champion.
Although Federer is one of only four men to have reached the final in all nine Masters 1000 events, he is yet to win them all. Similarly, even though the former World No. 1 has the most ATP 500 titles in history (24), some tournaments have missed out on witnessing the World No. 44 remain as the last man standing on their hallowed ground.
Without further ado, here are four big tournaments the 40-year-old has never won till date:
#1 Barcelona Open
In his defense, Roger Federer made only one appearance at the Barcelona Open, way back in 2000, before he even won his first Grand Slam. The Swiss maestro faced off against Sergi Bruguera in the first round and succumbed to a massive 6-1, 6-1 loss.
In the 22 years since, Barcelona has not seen the former World No. 1 return to its shores.
#2 Rome Masters
The Rome Masters is one of two Masters 1000 tournaments Roger Federer has never won. However, the Swiss has reached the final on four occasions in 17 total appearances.
In 2003, Felix Mantilla bested the 20-time Grand Slam champion to deny him the title. In 2006 and 2013, the 40-year-old was vanquished by Rafael Nadal, while it was Novak Djokovic who put an end to his dreams in the 2015 edition. The World No. 44 also finished as a semifinalist twice, losing to Djokovic on both occasions.
#3 Monte-Carlo Masters
The Monte-Carlo Masters is the other Masters 1000 event Roger Federer has never won. In 13 appearances at the event, the 40-year-old has reached the final four times.
The 20-time Grand Slam champion fell in three successive finals between 2006 and 2008 to Rafael Nadal while being the top seed on every single occasion. In 2014, compatriot Stan Wawrinka scored an exquisite comeback victory to deny the World No. 44 his maiden title on the French Riviera.
The Olympic Games is arguably the biggest title missing from Roger Federer's trophy cabinet. In four appearances at the event, the Swiss reached the final once, losing to Andy Murray in 2012.
In his maiden appearance in 2000, the World No. 44 lost in the semifinals to Tommy Haas and then to Arnaud di Pasquale in the bronze medal match to go home without a medal.
In 2004, the 40-year-old succumbed to a shock defeat against Tomas Berdych in the second round, while James Blake outdid him in the quarterfinals of the 2008 edition. However, the 20-time Grand Slam champion has an Olympic gold to his name in the doubles category, going all the way with Stan Wawrinka in 2008.
