Bryan Reynolds Sr says Juve's plans to loan him to Benevento saw the defender reject the Bianconeri.
He told the Italian Football Podcast: "The determining factor [behind joining Roma] was that Bryan wanted to go to a team where he was needed and would stay. With Juventus he would have to go to Benevento first. We didn't know how long they were going to keep him there.
"But Juventus were very interested and he was ready to go to Juventus. And Juventus had every intention to play him quickly. We learned that in Europe the younger players are thrown into the fire quicker than the MLS.
"But determining factor was Bryan wanted to go straight to a team, he didn't want to go the long way and then have to leave to go back to Turin. Roma gave him a straight shot at the non-EU spot, he loved it. He wanted to be in one place. He didn't want to pick up and leave and then have to go and learn another system and everything all over again.
