Federer, rather than losing confidence with that, practised day and night to prove himself.
"There was a coach at my first tournament who told me: At most, you can have coffee in a bar with those hands. You have no talent boy," The Daily Express quoted Federer, as saying.
The 36-year-old, who is also the world no. 2, revealed that his coach made him grow in anger and changed his personality.
"I got up at night to practise. I would put on the lights in the garden and hit against the wall hundreds of times. I hit forehands, backhands.every kind of shot until I could convince myself that each was perfect," he added.
