Juventus are dominating the transfer gossip pages in Brazil thanks to the presence of chief scout Renzo Castagnini.

Castagnini is currently in Brazil on the second-leg of his South American tour after spending last week in Argentina.

It's emerged he watched Gremio's attacking midfielder Douglas Costa in action. The teenager is also a confirmed target for Manchester United and Real Madrid.

Castagnini also made enquiries after Internacional de Porto Alegre midfielder Alex after watching him in Copa Libertadores action against Boca Juniors.
