Roger Federer: 'There were moments I wanted to walk away from tennis'

A stage before his name was immortalized and the records fell; a period in his glittering career when defeat was more common than victory. "It was tough," Federer tells CNN Sport, reflecting on his early years on the ATP Tour. "When I traveled internationally I would get beat up very often in the first round 6-2, 6-3. You go home and realize: 'Okay, you're good in Basel but you're not very good in the world.'"
