WATCH: Six-year- old imitates Federer perfectly

There's no doubting the influence of Roger Federer. Just take six-year-old Yunosuke and his perfect duplication of a Federer point.

Yunosuke and his little brother, four-year-old Koujirou have nearly 10,000 followers on their joint Instagram account, which is full of videos of them playing tennis.

Koujirou is just as capable of imitating Federer's perfect strokes.

Federer signed with the Japanese company Uniqlo last year, no doubt increasing his popularity in the Asian nation.
