Juventus are in talks with Gremio about first refusal on young pair Douglas Costa and Felipe Mattioni.

Juve chief scout Renzo Castagnini watched both players during a scouting trip to Brazil this month and the Bianconeri are now seeking first option on the duo.

Attacking midfielder Douglas Costa and fullback Mattioni are targets for some of Europe's biggest clubs and Juve are reluctant to discuss a fee until next summer.
