Juventus great David Trezeguet says the club blundered allowing Bayern Munich winger Kingsley Coman to leave.

Trezeguet admits he'd also like to be involved with Juve at some level.

"I believe that a former player like me can be useful alongside a coach, a manager and a president," said the 1998 World Cup winner to Gazzetta dello Sport.

“Juve's biggest mistake was letting Kingsley Coman go away. On the other hand, their best coup was taking Cristiano Ronaldo because no one was expecting CR7 in a club that has always had great attention to the budget in its DNA.

“Of course, there were some problems with his teammates, but Ronaldo scored 100 goals. I believe that no one has been able to manage him like Zidane. Perhaps Juve lacked a certain dialogue."
