Brazilian teen ace Lanyan is a target for Chelsea and Juventus.

The Sun says the Vasco De Gama full-back, tipped as the new Roberto Carlos, has earned rave reviews for his impressive youth team performances.

Chelsea scouts have watched the 17-year-old three times.

But Juventus may have the upper hand as Guus Hiddink has said he will not interfere with transfer policy during his temporary stint at Stamford Bridge.
