Iachini worked with Dybala at Palermo.
He said, “He likes to play all across the attack, maybe in a 4-3-3 his movement is limited to just one side. It's therefore logical that you'd see him less on the pitch.
“Paulo is a champion though, he just has to find his sheen.
“I don't think he's being obscured by [Cristiano] Ronaldo and [Federico] Bernardeschi, who are just in better condition than him at the moment.
“I think these periods can happen during a season and Allegri has shown that he knows exactly how to manage the big squad he has. It's just a question of time, everyone will find their best condition.
“I don't think Juve will let him [Dybala] go in January. They've already sold [Gonzalo] Higuain, it's hard to see them making two big sales in such a short period of time.
“The Bianconeri want to win and a player like Paulo is always needed. Personally, I'm just waiting for the moment he gets back to his best."
