It has been reported by La Gazzetta dello Sport that both Juventus and Inter agreed on the terms that the former would have to pay the latter a fee of €500,000 if Hernanes made at least three appearances in the Champions League for Juventus this season.
The player signed for Juventus on transfer deadline day for a fee of around €11 million.
However, the former Lazio star has failed to establish himself in the Juve starting XI since his move.
If Juventus secure a place in the knockout stages of the Champions League, they will have to pay a further €500,000 to Inter, which would form a total sum of €1 million in bonuses.
