Roger Federer has pretty much done his job for the current season the only remaining chapter yet to be decided is the Nitto Atp Finals in London. At O2 Arena, Federer will try to clinch his seventh ATP Finals title and the first one since beating up Jo-Wilfried Tsonga for the 2011 edition's glory.

Last week, Roger Federer traveled to his hometown Basel in Switzerland to feature an ATP 500 event he holds dearly in his heart. When the dust settled, he was the only one standing up waiting for his eighth crown at that event. Regarding Federer's saga, Swiss Indoors Basel should be a point to focus on in the years to come as it may easily go down as the last official event for Federer who has signed a contract that will have him competing there up until 2019.

Two years from now, a jam-packed indoor venue and millions on their own home-based sofa might be bursting out crying while watching Federer's last official ATP match.

With Roger Federer swarming around there are no sure bets

A year ago, not even Federer's most dedicated fans wouldn't have thought that their tennis god may be one of the men's tennis poles in 2017. He and a resurgent Rafael Nadal have completely dominated the tour like in their primes. For Federer, even winning another Grand Slam used to be a distant well-hidden thought, let alone dominating the ATP circuit. Entering the Nitto ATP Finals, he holds an impressive 49-4 win/loss ratio.

Witnessing such a comeback would make it difficult for all those who might want to try to predict an official date to his retirement from tennis.

The pieces of information are thin, and there is no certain direction to point into. A while ago, Federer made his intention clear by choosing a reduced schedule throughout the year in order to gain extra points in the longevity compartment.

Federer gets emotional while witnessing a retirement event

Swiss Indoors Basel marked one of Roger Federer longtime friends' retirement.

Aged 36, Marco Chiudinelli, also a Swiss representative, chose this event to make his last bid before calling it a tennis career. An in-form Robin Haase swept local guy Chiudinelly away, but the intriguing part came right after.

Roger Federer was in the stands, and he was one of those who personally greeted Chiudinelli in the end.

Flirting in the vicinity of retirement concept, Federer got extremely emotional maybe thinking how he'll handle that day yet to come when he will be walking in Chiudinelli's shoes.

Two years from now, Federer will witness his contract with Swiss Indoors Basel tapping on the expiration date. Moreover, he will be well past the 38 years of age milestone at the time. All these may hint into his retirement official date although nothing has ever landed within rational limits on this matter.
