Roger Federer is considered by most to be the greatest tennis player of all time. Winner of 17 Grand Slams and a record 302 weeks as Number 1 in the world cements his status.

Currently ranked at Number 7, The Fed Express reached the semi finals of the ATP World Tennis Finals in London this week with a stunning comeback against Del Potro, but lost to Rafa.

He proved a bit more elusive at this year’s event than previously, travelling by car and not boat, so opportunities to get his sig were limited. Prior to his semi, he did a 30 minute warm up and signed for a large throng, using the same Sharpie throughout! So the distinctive ‘graph is on the light side, but a graph nevertheless.
