He is vital to us, sure, which is exactly why he needs to understand what he did to the club and his team.
Him sitting out for an extended period is a boost for Dybala who needs to take advantage of any game time he gets during that ban.
In any case, Costa said something (if you believe Calciomercato lol) that is along the lines of "you don't know what he said to me"...so, has anyone else reported that after he made his apology?
