The man is a phenomenom and has to be considered the greatest. Really, only Nadal and Djokovic are in the GOAT conversion and both would have valid claims. However, not only has Fed won more slams, will Nadal and Djokovic be reaching slam finals and finals when they are 34/35 years old like Fed has done? I would suggest not. 35 years old, surgery and off the circuit for 6 months, then comes back straight into the Australian open in his first proper tournament and reaches the semi final playing sublime tennis. It's just insane. The man is a god.
