At the start of the tennis season some of my friends were claiming that Federer was at the end of his career. ‘He is just too old, ‘he’s not challenged enough’,'I would quit now with all the glory on my shoulders…’ were just some of the sentences I used to hear. But then Roger surprised the world by winning his seventh Wimbledon and became number 1 again. Then I thought: this is something only the biggest stars can achieve, and started designing the infographic. I think data speaks by itself and now there is no doubt that, so far, Roger Federer is the best tennis player of all time.
