Fed already has one gold medal in his ever-expanding trophy cabinet.
Along with Stanislas Wawrinka, the pair won the doubles at the 2008 Beijing Games.
But an individual gold is what the GOAT needs to complete the greatest career of all time.
If ever Federer needed the extra motivation, he will be the flag bearer for Switzerland at the opening ceremony of London 2012 and won't want to let his country down.
At the start of the season, many felt that the Olympics, being held at Wimbledon, gave Roger his best chance of adding to his impressive resume.
And that playing on his favourite surface in best-of-three sets played right into his Swiss hands.
But then, he went and won Wimbledon, leaving many thinking is there no end to this man's lust for titles?
But, of course, Federer won't be the only contender for the Olympic gold.
Novak Djokovic, Rafael Nadal and Andy Murray all have legitimate claims and high expectations heading into the games.
Djokovic is probably still scratching his head and wondering where it all went wrong during his semifinal Wimbledon defeat to Federer.
Who will win the individual gold medal in tennis at London 2012?
Following his shock second-round exit at SW19, Nadal will be keen to get his season back on track after an unbelievable clay-court season, which saw him win a record seventh French Open.
And Murray, the first British man to reach the Wimbledon final since 1938, will feel that on grass and in best-of-three sets, he's capable of beating any of the top three, particularly in front of a home crowd.
But Federer remains the favourite.
The Swiss man's movement, power, shot-placement and variation seemed to have reached new levels during his Wimbledon final victory over Murray.
Jo-Wilfried Tsonga, David Ferrer and Tomas Berdych will also feel they have a chance to win medals.
But Roger Federer is the man best-placed to win gold.
